I wouldn't make a T-shirt quilt either, LOL!! I did put together some vintage blocks for a guy from his grandmothers stuff. I provided the batting and backing, added borders to some of the blocks to make them all the same size, quilted and bound it. He paid $300, and it wasn't a queen size, it was more like a twin. Your time is more valuable than $8/hr. I used to charge $12/hr for simple projects like making pillows and such, and that was a few years ago.
