You being a musician and most likley appreciate the art that goes into something like a quilt. As long as you are not hung up on perfection and types of materials like 100% cottons and high quality fabrics from famous designers.(don't take offense anyone these fabrics are top notch and outstanding if you can afford them,I am only speaking to those on a buget here)
Back on track here lol, Any way if you are the creative artistic , throw caution to the wind type you can make quilts for fun with about anytype of fabrics and not even worry bout matcy matchy;) .As said before yard sales, flea markets thrift stores etc. I have never paid more than 2.99 for an entire quilt backing. That is including a king size. I find sheets all the time at the local good will. never more than 2.99!
