One of my guild members does many t-shirt quilts. Just this Saturday, I overheard her say $500. I think that was $500 plus the cost of backing and batting. She makes me laugh. After each t-shirt quilt she declares that this is the last one! Then a couple of weeks, not months, later she is working on another because she can use the money! She stews and grumbles and proceeds to make a beautiful collage of shirts to honor someone!
