I have made several projects from my husband's shirts. You will be amazed how much fabric can be garnered from a shirt! The first projects were for our children and made into 38" wall hangings and several others that are smaller hangings using Dresden plates. This winter I made a queen size quilt for myself--and I still have the backs from the shirts waiting for another inspiration! Granted, these projects were "scrappy" but there is a lot of fabric in a shirt. I found most of his shirts were poly/cotton blend and a few were more "rayon" but I put everything in and it works. If you are contemplating jersey, I'd put a backing on that because it is so stretchy. I found the poly/cotton blends looked nicer as poly holds color better than straight cotton so still looks fresh in the recycling. Too,I think it is a stronger fiber.
