When I first started quilting I mixed decorator fabrics, new cotton fabrics, and recycled clothing from the thrift store. They are all still in use and no one has complained about how they feel. I still do this sometimes with scrap quilts, but now that I have a good sized stash I don't do it so much. Sometimes I make a quilt just from the decorator fabrics that DD and I made purses from several years ago. I still use a lot of thrift store fabrics because sometimes I run across such a unique pattern or a great color I just can't resist.
