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.

The class was good but I had some problems.
Some of the measurements just didn't add up. For example, I couldn't get the back armhole right. Despite checking measurements multiple times the back measurement jutted out past the armhole depth, making a weird shape. In the end I just free handed my own armhole which worked ok.
Some things just didn't make sense. For example, Sanae used the no-dart front sloper to cut her muslin and then added a dart to the muslin. Made me wonder why we made a darted sloper. Anyway....I will use the darted sloper and see what happens.
Overall, quite a good class but will need to look at other videos on how to make a sloper.

I have Sanae's book but I needed the visual to see how she makes her sloper. Watching the video clarified the steps for me.

Very thorough and a great complement to Sanae's book. Really enjoyed her method and relaxed teaching style.
