Sinclair Valley Knit Skater Dress with modified half-circle skirt from Flared skirts ADD-ON, size P6, pockets, upcycled from mystery polyester knit nightgown with low stretch

Back in 2018 Lea Kissner and I talked about the need for a new privacy conference over dinner. Lea noted that there wasn’t a conference where privacy engineering practitioners could meet and talk about the solutions they implement in practice. Most existing privacy conferences were targeted more at privacy researchers or privacy lawyers. Lea had worked as a privacy engineer in industry for many years and I had co-founded a privacy engineering masters program and also had experience starting and running conferences. So Lea convinced me that we should work together to start a new conference. In August 2019 we met in Santa Clara, CA for the first USENIX Conference on Privacy Engineering Practice and Respect.

PEPR 2019 went well and we had planned to continue PEPR as an annual event in the Bay Area, as that seemed to be where most of the privacy engineers are. COVID derailed this plan and PEPR 2020 was held entirely online. The USENIX Association (and every other organization that runs events) struggled through the pandemic and decided they could not afford to run PEPR 2021 online as well. So, the Future of Privacy Forum and Carnegie Mellon University CyLab stepped in to co-host an online PEPR 2021 event and I presented my talk “Illustrating Priavcy Engineering Concepts with Potty Talk” from my third-floor bathroom. USENIX ran PEPR 2022 as a hybrid event (I remotely presented a talk on the design of cookie consent interfaces from my kitchen) and then returned to fully in person in 2023 and has been running PEPR in person ever since, but unfortunately I was not able to attend in 2023 or 2024.

I decided that I needed a pepper dress to wear the next time I attended PEPR in person. Most of the pepper fabric I could find was quilting cotton. I could not find any knit pepper fabric that I liked. I thought about custom printing some pepper fabric, but never found a design I really liked. A week before PEPR 2025 I decided I really needed a pepper dress and scoured the internet for suitable fabric that I could get delivered to my home quickly. Again, I mostly found quilting cotton.

I noticed that pepper PJs in knit fabrics were readily available. So I decided to order a size XXL pepper nightgown and try to cut it up and turn it into a dress. Two days later, the nightgown arrived and I got to work figuring out what to do with it. The website claimed it was 95% polyester 5% spandex knit, but the garment tag said it was 100% cotton. It feels more like polyester to me and a drop of water beads on the top. It only has about 30% stretch so I’m not sure about its spandex content. The fabric features bright red peppers on a dark grey background with black outlines.

I decided to use the Sinclair (free) Valley Skater Dress pattern with a half-circle skirt from the add-on pack. I have made this pattern previously and it was pretty easy and I thought I could adapt it for this project. Because the mystery fabric did not have a lot of stretch and I know the bodice is very fitted, I decided to size up to a 6p rather than using the 4p size I had used previously. I extended the bodice by about an inch and a half as suggested when making the dress without a waistband. I cut the nightgown open at the side seams and projected the two bodice pieces onto it and cut them out, leaving the neckband and shoulder seams from the nightgown in tact.

Then I projected the sleeves onto the fabric from the nightgown sleeves and cut them out with the hem in tact so that I would not need to hem the sleeves. Finally, I had to figure out what to do about the skirt. The nightgown was not quite wide enough to cut out the pieces for the half-circle skirt. I decided to improvise and pivoted the sides of the skirt pieces in until the fit the fabric I had. I left the bottom hem in tact (and thus, not quite as rounded as the pattern called for) and I reduced the rounding on the waist and made sure it would fit the bottom of the bodice. I ended up with something closer to a one-third circle skirt than a half circle skirt.

I really wanted to add pockets to the dress but didn’t have enough nightgown fabric left for deep pockets. I decided to use scraps of cupro jersey from another recent dress project to make the pockets. This is a super lightweight and not very stretchy knit and it worked really well (although it would have been slightly better if it were dark grey to match to dress fabric) — now I want to use it for all my knit pockets. I followed the pattern for inseam pockets but extended the pocket bag a bit to make them slightly deeper. The pocket construction took as long as making the rest of the dress — reminding me of how much I hate assembling inseam pockets. The part I really struggle with is stitching the top and bottom of the pocket openings without catching any of the pocket bag on the outside of the pocket. After trying and failing on the first pocket I unpicked it and used my trusty glue stick to line up the pockets and then sewed them with my edge foot. It still took way too long!

After I assembled the pockets it was easy to attach the skirt to the waistband. Since everything was already hemmed, I added a label and I was done… until I looked at the back and noticed a lot of bunching at the waist.

I decided to add a simple swayback adjustment, and then I was really done.

And then it was time to accessorize! I ordered a bag of plastic pepper charms and added jump rings to turn them into pendants.

This morning we presented our UsersFirst framework at the PEPR conference. As you can see I was fully on theme with pepper dress, necklace and socks. And the pockets came in handy for the microphone pack.

Scrunchie Burrito

Posted on by

I had a bit of leftover rainbow fabric from the skort and decided to make some matching scrunchies. I have never sewn scrunchies before, so I searched for instructions online. There are lots of instructions available and I found two that looked reasonable and gave them a try. The first one involved sewing the long end, threading in the elastic, and then layering the shorts together and sewing the loop closed with a sewing machine. This resulted in an ugly and not quite aligned seam, especially with the slippery stretch fabric I was using. The second technique called for hand sewing the end, which worked, but took more time.

I decided to look further and found a video and instructions for the burrito method, which allows you to make scrunchies with perfectly aligned seams and no hand stitching. This involves a bit of a geometry trick, as you need to make a donut and then turn it inside out. In the burrito method you cut your rectangle (I used a piece 4″ by 23″) and sew the short ends together to form a loop. You fold your loop in half, right sides together, folding in parallel to the seam. Then you fold the top layer in on itself and bring the bottom layer sides up around the folded in part and carefully stitch the long edge without catching the top layer. As you go you pull the top layer through until you have stitched almost all the way around the (inside-out) donut. You leave a small gap and then turn the whole thing rightside out. Then you thread the elastic in (I used 8 inches of .5″ elastic), sew it into a loop, and then close the hole in the seam. I did all the stitching on my serger except the final hole closing. I didn’t press or pin anything and it was super fast to make!

Pocket scarf

Posted on by

I had carpel tunnel release surgery on my left hand this week (I did the right hand a month ago), and its healing well but I have to keep it bandaged up for a week. A polar vortex is forecasted here for the coming week and I was concerned about not being able to fit a glove over my left hand. I thought about sewing a large mitten, but I saw the free pattern from Sinclair for a Mojo scarf with pockets, I decided to give it a try. I do, after all, like to put pockets on everything. The pattern comes in Sinclair’s full range of sizes, in a narrow and wide width, and with the option of adding a hood, ears, and cape. I went with my usual size 4p, narrow width, and hood. I decided I didn’t need a cape and ears, although those could be fun too.

I used leftover Polartec sweatshirt fleece from a sweatshirt I made recently, and sewed it with the fuzzy side out. The fabric is about 70 inches wide so I cut the length of the scarf as one piece and chopped off some of the end for a pocket. This resulted in a scarf that was slightly too short, so when I realized that I added three inches on to each end. You can see the extra seam near the bottom of the back of each pocket.

It was pretty straightforward to sew, but took longer than I expected. I guess it is just a lot of fleece and layers to sew as everything is double-layered, which makes it warm and reversible with a nice clean finish. I sewed almost all of it on my serger (except for some basting, topstitching and closing the seam in the back after I turned it right-side out), and was glad to have a machine that could easily sew through so many layers of plush fleece.

Scarves, scarves, and more scarves

DSCF7849Last summer I took photos of a bunch of my favorite paintings by Grandma Gladys (see also this article about her and this TV interview), and then turned them into fabric designs on spoonflower.com. I then turned a couple of my favorite designs into infinity scarves, and when I told Grandma about it, she requested one of each. It has taken me a while to make this happen, but with the help of Jen Primack of Upcycled Designs, I now have a big stack of infinity scarves ready to ship to Grandma. These were all printed by Spoonflower on performance polyester. They each use a half yard of fabric (so you get 2 out of a 1-yard cut). Fabric is folded the long way, sewn in a tube inside out, joined at the ends with a small opening, turned right side out, and the opening stitched closed.

I setup a tripod and took a lot of selfies so you could see all the scarves. Since I had enough fabric for 2 of each, I’m keeping the duplicates of some of my favorites for myself… but so hard to decide!

Tartan Tango, now in scarf form

Lorrie modeling Tartan Tango infinity scarf

A few months ago I got a request from the powers that be at CMU to design a scarf based on my Tartan Tango quilt design that they had commissioned when I was on sabbatical back in 2013. I was happy to oblige. I dusted off my Interleave quilt design software and produced a fabric design based on the quilt. After experimenting with the design in both a large and small size, we settled on the smaller version.

But they wanted 50 of them ASAP, which is well beyond what I could possibly sew in a week (or even a year given my current schedule). So I ordered a huge bolt of fabric from Spoonflower and subcontracted the sewing to Jen Primack of Upcycled Designs.  Jen cut the fabric and sewed it on her serger, and was able to deliver the first half of the order within a few days, and the second half not long after.

I also learned a bit about scarf packaging, and acquired suitable glossy white boxes and gold “stretch loops” for a finishing touch (yes, that is the proper term for those gold elastic cords, tied in a bow, that decorate small packages… I just learned that).

I have another slightly smaller project in the works that Jen is helping me with, and will sew a few more scarves myself with fabric I designed from Grandma Glady’s paintings.

Password fashion and home decor roundup

Bad password fabric

I’ve been collecting images of all the cool things that I and others have made with my bad password fabric. The fabric is available from Spoonflower in three size and both with and without the naughty words. It has a purple background and includes 501 passwords. Spoonflower offers a variety of different kinds of fabrics, including a performance knit, basic cotton, and faux suede. They also will print this design on wrapping paper and wall paper.

Recapping for those who are just seeing this, I designed a series of bad password fabrics based on the most popular passwords stolen in a Rockyou.com data breach. First I made a “Security Blanket” quilt printed on basic cotton fabric in pastel colors. This quilt appeared in Science Magazine and was on display at the residence of the Carnegie Mellon University president for most of last year. Then I designed a purple version of the fabric and made a password dress with performance knit fabric. The dress has gotten some nice press on CNET, the Trib, and the Women you should know blog.

Then my friends started requesting other password apparel. Mary Ellen Zurko commissioned my friend Jen Primack of Upcycled Designs to make her a t-shirt from cotton knit fabric. Then Jeremy Epstein asked for ties, and we found Jen Knickerbocker of LoveCrushDresses and got her to offer regular ties and bow ties in her Etsy shop. The ties are made from cotton sateen.

Then Jen Primack bought an old chair and reupholstered it with my passwords fabric in heavy cotton twill. Doesn’t it look great in my living room?

Kristin Briney emailed me to tell me she had made a password dress from cotton poplin. And I just made a password infinity scarf from silky faille (a woven polyester).

Password baby quilts and couch throws made out of kona cotton are coming soon….

In the mean time, I’ve gotten many requests to wear the password dress to events. I wore it to give an invited talk at the 2014 Grace Hopper Celebration of Women in Computing (where I was referred to as a “password researcher and fashion idol“). I also wore it to a couple of briefings I gave to Congressional staff on Capitol Hill.

And for those wondering about the different types of fabric. The polyester fabrics are much brighter than the cottons. They are all fairly consistently bright with nice saturated colors. My favorite is the performance polyester, which doesn’t wrinkle and has a little bit of stretch and a nice drape. But it’s not really what you want to use for a quilt or a tie. The kona cotton is a little disappointing because the colors print a little dull. The basic cotton (which is similar to the kona but slightly lighter weight and less expensive), cotton sateen, and the heavy cotton twill produce brighter colors. They aren’t as bright as the polyester, but they are noticeably brighter than the kona cotton. The cotton silk also does not produce bright colors. I think the polyester silky faille might work well for ties and some other applications where you might otherwise use a woven cotton but want brighter colors. It’s a little slippery and harder to work with than cotton though. I got samples of the polyester faux suede and polyester eco canvas. They are both lovely bright fabrics, but I haven’t made anything out of them yet.

1/22/15 update: Von Welch, Director of the Center for Applied Cyber Security at Indiana University Bloomington wore his Password tie for a local TV interview. The reporters loved the tie and commented on it at the end of the interview.

6/28/20 update: Given current circumstances, password masks were required! I printed my design XX small on cotton spandex jersey and lined the inside of the mask with fabric from an old cotton spandex t-shirt (outer layer and lining each cut 10.5 x 5.5 inches; sewn together at top and bottom; left and right sides folded in and stitched to make a casing on each side; long 1-inch strip of stretchy t-shirt fabric pulled through the two casings and tied to make 2 loops to go around the back of the head). Spoonflower also sells masks already made (and lots of other things) for those of you who don’t sew.

To infinity… and beyond!

Posted on by

While I often imagine myself making homemade gifts for everyone on my list, that doesn’t actually ever happen. This year I got a fun idea for one special gift, and liked it so much that I decided to make several more on a similar theme. This year was the year of the infinity scarf (a scarf with the ends sewn together in a loop). But not just any old infinity scarf…. this year I designed three original fabrics, had them digitally printed at spoonflower.com, and turned them into infinity scarves.

The first scarf was inspired by a colorful painting that my grandmother made earlier this year in her art class. The painting is framed and on display on a shelf in my kitchen. I love the bright-colored swirls and spirals, reminiscent of my own doodles, and thought it would look lovely on a scarf. I took a digital photo of the painting and loaded it into Photoshop. I played with it a bit and realized that all I needed to do was tile it in a mirror-image pattern to create an absolutely stunning design. The shapes in the painting combined with their mirror images to form new shapes and an intriguing pattern.

I uploaded the design to spoonflower and ordered two yards of performance knit fabric, a washable polyester knit. Then I waited about a week for my custom fabric to arrive in the mail (the worst part of using spoonflower is the wait!).

Two yards is enough fabric to make three infinity scarves using the free pattern from Sewn Studio’s Jersey Infinity Scarf Tutorial. The tutorial was super easy to follow. The hardest part is cutting two yards of this slippery fabric into three 24-inch pieces. I made my first scarf in less than an hour and was quite pleased with the results. The scarf can be worn long, or looped around twice. It can also be knotted in various ways for a different sort of look – although one of the great features of infinity scarves is that you don’t have to mess around with tying them. I made three scarves – one for Grandma Gladys, one for my mother, and one I kept for myself.

I decided to try my hand at some more fabric design. I went back to the Processing computer program I had used to design my Interleave quilts and adapt it for fabric design. My first design is based on my Interleave #3 quilt. I used the same pattern and color scheme, but added gradients so each bar is a lightly different color. The addition of the gradients adds dimension to an otherwise flat design, and makes it almost appear to glow.

My second design was based on my Interleave #4 quilt. Here I completely changed the colors and used gradients to not only add dimension, but also to introduce more colors. I love the way the colored stripes mix to produce the illusion of additional colors. Here you can see the fabric pattern, as well as the scarf being modeled by me as well as by my mother-in-law.

The infinity scarves were big hits. Here you can see them modeled by my grandmothers and by my mother. Grandma Gladys, second from the left below, made the painting that is featured on the fabric. (Did you guess that we all like purple?)

These fabrics are all available for sale from my shop at spoonflower. You can have them printed on your choice of fabrics (or even wallpaper or gift wrap).
