Past Student

Patternmaking: Draft a Sloper for Your Body

I was really hesitant that I would learn anything about patternmaking in such a short time. Katy did such a good job at breaking down the main concepts and I was pleasantly surprised at how much I learned.

Class Description

Anyone can sew their own clothes! It just takes a little imagination, some instruction, and practice.

Learn flat patternmaking by drafting a custom sloper from your own body measurements in Patternmaking: Draft a Sloper for Your Body. In this intensive, students learn how to use their measurements to create a fitted bodice block and a fitted skirt block. Each student cuts a muslin version of her pattern for a fit analysis in the class. As a group, students discuss pattern corrections for improving fit on future versions of their sloper block. This class is perfect for those who want to learn how to draft their own sewing patterns or for those who are interested in flat patternmaking.

If you’d like to learn how to use a sloper to draft sewing patterns, check out Patternmaking: Creating Style Variations from Basic Pattern Blocks.

As part of our Learn to Sew classes, patternmaking instruction is taught with an emphasis on key industry skills and techniques to create garments that look well-made. All of our sewing and patternmaking classes are both fun and productive, instead of just one or the other. We encourage anyone who is interested in sewing clothes to join us for our sewing classes, whether you are strictly a hobbyist or interested in learning clothing construction skills to bring your original fashion designs to life.

Our studio intensives are like taking a 2-day sewing vacation, and we’ve taught wonderful students who have visited us from all over the world. We invite you to spend two days working with us in our inspiring and friendly studio. After our patternmaking class you’ll start your week with lots of excitement to continue your sewing adventures at home!

  • The key body measurements needed for drafting a bodice sloper and skirt sloper.
  • How to use flat patternmaking techniques to draft custom slopers based on your body measurements.

Our Expertise and Approach

At Workroom Social, we teach adults how to sew clothes that fit their individual styles and unique body shapes and sizes.

We create a supportive and non-competitive environment in all of our classes. Perfection is never our goal in the classroom. Students should expect that their skills will improve with practice over time.

Our team of professional designers and sewists make garment sewing approachable, and it’s our goal to provide students with the confidence and the knowledge they need to continue practicing sewing at home.

Our Belief in the Power of Sewing

Through sewing we build communities, stimulate creativity, and help improve women’s self-esteem and confidence by empowering them to sew the clothes they want to wear.

We work hard every day to promote a sense of accomplishment in our students and customers by reminding them of their abilities. Together we learn from each #sewingfail and celebrate every #sewingwin, no matter how small.

We use our shared passion for sewing to connect with those we might not meet otherwise, and we create opportunities for our students to develop relationships that go far beyond sewing itself.

About the Instructor

After working around the world in biomedical laboratories with a doctorate in biochemistry, Katy Patzel decided to develop her interests in patternmaking, fit, and construction by pursuing a second career in the fashion industry. She then completed the Fashion Design program at Parsons School of Design, and has interned at various designer and luxury brands. Katy now works as a patternmaker in New York RTW for both men and women. You can see her most recent work on Instagram.
