"Everyone has a beloved t-shirt. Now you can sew a whole wardrobe full of them after you learn how to draft your own pattern for a perfect-fitting tee. Cal will show you how to take proper measurements and turn those into a pattern. From there, you can customize your basic pattern to adjust the sleeve length, the neckline, the length of the t-shirt and much more. These are fabulous pattern drafting skills that will take your sewing to the next level."
