Just remember the fleece will not be "raggy" when its washed like the flannel will. Not sure if you mean you are mixing fleece and flannel in the same quilt or not, so I just wanted to mention they wont act the same. (Unless you mean you are going to use the fleece as batting and if thats the case you are good to go). Hope you find your pre-cuts, I cant offer any help on that front.
