I made a rag quilt using cotton on the front a layer of flannel in place of the batting and then backed it with flannel. It ragged up wonderfully. It isn't too heavy and keeps me warm while watching tv. Let me look for the link to the pix here on the board.
Here it is!

This was just one time through the washer and dryer after finishing it and I haven't washed it again. My only gripe is the pilling on the golden yellow backing. I had used a dark blue flannel to keep with the UofM colors. It is only on the backing so it isn't that big of a deal to me.
