I made a lightweight throw many years ago, flannel front and back and used a real thin batting inside to give it more stability--not too bulky. I just used big squares of some scraps. Its not real big--I can tuck my feet under it but its not as long as the couch. Then just stitched in the ditch. Hadn't had any problems with the layers separating or with any thing else associated with it. It wasn't meant to be prize winner, but it works.
