I made two recently without a pattern, pre-washed my flannel and made the mistake of using Warm and Natural batting cut the same size as the squares. Boy, was THAT a mistake!! The next one I used an 80/20 batting cut 1" smaller and it was better. Next, I might just use flannel for all three layers and 3/4" seams. I pre-washed the flannel with color catchers and then washed it again when finished with color catchers and dried in the dryer and the colors still ran! I have washed it twice more, and I still can't believe the amount of lint I get! They are getting well-used by my grown son's while watching TV and they aren't complaining, so it wasn't a total waste. I can't wait to make another, this time using squares and rectangles with the flannel I have.
