Hello all, First off, I apologize if this message is a duplicate. I got an error with the first attempt. I am ready to place my first order to Midwest for transfers and I need some advice on material. I am putting logos left chest and numbers on the back. Tees are 100% cotton. Henleys are 60/40 cotton/poly blend. Also, what is the most common number size for the backs? No names, just numbers. LuAnn @ Image Embroidery Because Your "Image" Matters
