you need to buy the higher end flannel or buy the flannel sheets. I first did that because I had a quilt I did not want to piece the back for. I loved it. Not knowing the fabric, I did wash it first (I do not normally prewash) and it came out with minimal shrinking and so soft. After that I have not prewashed the sheets. I use these with lightweight throw size quilts that we give for going to games because they are warm (or folded, they are good to sit on) and yet easy to roll up and carry and launder.
