Choosing T-shirt Medium size or bigger 1) I cut the T-shirt (dissemble) into a back part of body, front part of body, and sleeves. 2) Place the back part of body pattern on the T-shirt Where a Logo or decorative element on it's side. I arrange the pattern on top of a logo or a decorative element that goes on the center of the back part of body pattern. 3) Place the front part of he pattern on to other side of T-shirt. 4) place the sleeve part of pattern on the sleeve part of the T-shirt. I use existing hem on the T-shirt. Option) you can use different color of a knit fabric for the sleeves as I did for my up cycle project. 5) sew them! If you have any question please post a comment:) I'm more than happy to help you!
