There is a ton of work that goes into a T-shirt quilt and I don't like making them, have made 2. I charge like Onebyone's guild does, $20 a shirt with a 12 shirt minimum and not all shirts will not be allowed. I had one parent who brought ribbed white tanks that are undershirts, told her no way could these be included. Usually people hear $20 per shirt and rethink wanting the quilt and that is fine with me but if I am going to do it I am going to get paid for the pain of it.
