You are ready to start cutting! Yay! This is the fun part.
The first thing I do is cut off the sleeves, then I cut up the sides, essentially cutting the t-shirt in half.
I do this because:
#1, if there is a design on the front and back, I like to cut each side out separately.
#2 I keep the left over jersey material and put it in my scrap piles for later. I have used the leftover jersey for extra blocks in my quilt, binding, and many other non-quilting related projects (they are great for making toddler pants!).
