I made a rag quilt using old blue jeans and flannels and use plain flannels as batting. I cut 9" square of blue jean material and plaids for the back then I cut a 8" square of plain flannels for the batting. Sandwiched the 3 layers together then machine quilt them then sew all the squares together. I may not explaining this too good. Please let me know if you have any questions. It was real fun and easy to made plus I used up some old jeans and fannels. I like that idea.
