Draft and Sew a Torso Sloper and Muslin
Intermediate | 1 hour 51 sec
Sewing your own clothing is incredibly empowering and even more so when you've designed a clothing pattern customized to your unique body. The foundation of drafting patterns is a sloper, also known as a "block," which is a 2D version of your 3D shape. Author, illustrator, and designer Sanae Ishida teaches you how to draft your own front and back upper body slopers by taking your measurements, transferring them to Swedish tracing paper, making the slopers, and checking the fit of the slopers by sewing a muslin. She also demonstrates how to create an optional bust dart. Once you've completed your upper body slopers, you'll have the tools you need to draft patterns for shirts, coats, and dresses.
Here’s what you’ll need:
  • For the slopers: Drafting kit (Swedish tracing paper or large pieces of paper, ruler, pencil)
  • French curve

I can't believe how easy it seemed to me to create the sloper thanks to the fantastic teacher who is incredibly clear and calm! I really loved this class.

The explanations were very clear and paced well. I learned from doing, made two sets of slopers and am now pondering my armhole gaps. Very instructive. Important not to aim for perfection, just reasonableness.
