1. Cut out your 18″x18″ jersey squares. I used two flat t-shirt sheets and a stack of white t-shirts for my jersey. I cut out a sample square, labeled it as such with my fabric pen and then used it as a template to cut around for all of my other squares. One note- with all of the gathering that comes later, the 18″x18″ can be approximate- don’t worry about making perfectly uniform squares.
