Draft and Sew a Sleeve Sloper and Muslin
In the clothing design and sewing world, drafting sleeves can seem intimidating. Author, illustrator, and designer Sanae Ishida thought it was intimidating too before researching many different methods in order to develop a simpler, easier way. The foundation of drafting a sleeve is a sloper, also known as a "block," which is a 2D version of your 3D shape. Sanae teaches you how to draft a sleeve sloper by taking your arm measurements, transferring them to Swedish tracing paper, making the slopers, and checking the fit of the slopers by sewing a muslin. To create a finished garment, you will also need front and torso slopers, which can be made in her Torso Sloper class. With a finished sleeve sloper, you can design short sleeves, long sleeves, puff sleeves, bell sleeves - all different lengths and shapes to build your dream wardrobe.

The drafting of the Sloper was lengthy. I will revisit the class to get some clarity on the measurements.
