I just made a denim and red plaid flannel one for my son for Christmas. I used old jeans, cut 9 inch squares, sewed an X, no battings because of weight of denim and sewed 1/2 inch seams. On the outside I sewed twice around the border, washed and dried it. Really liked the way it turned out. If I was not doing denim, just flannel, I think I would do 3 layers of flannel.
