I tend to quilt with anything that falls on my hands. I have used even the upholstery samples that come stappled together for showing. I have a friend who gave me some when a line became discontinued and that quilt I made was great. A little tough to quilt, because is very high count threads, but with a jean needle, is doable. I also opened my seams, rather than folding to the darker, since with that thickness nothing will show.
I have also used terry cloth, minky, silk, and even embroidered organza. You name it. One of my next ones is going to have lace and a brocade I got in NYC. Just let your imagination roll and don't stop by rules. Set your own. You will find some difficulties along the way, but you can figure out a way to overcome them.
