I gave away a couple of shirts One of which was the poly blend and one was 100% cotton. Both were extra large mens t's and the poly blend was jerzees and the all cotton hanes I believe. AS it turns out the all cotton did not fit--too tight. As I think about it does the hot wash to remove excess dye cause the extra shrinkage. I know that to dry the shirts I need to go to medium heat otherwise they are damp. I do not dry on hot cotton setting. I plan on using all cotton since the colors are more vibrant but do I need to go up one size? What are your thoughts guys? I plan on doing shirts with transfers on the front so I do not want to have sizing and shrinking issues. I will apply the transfer on the finished shirt.
