I've made lots of fleece rag quilts, they are great because they don't "shed" and I've used whatever fleece I found in the remnant bin. I've mixed different brands together, I've tried to make sure when I layed out a pattern that the stretch all went in the same direction but when it didn't, there didn't seem to be a problem, I've made some two layer, and others only one layer. Fleece is wonderful to work with. Here's a front and back picture of a two layer one I made, and a couple of one layer ones I've made.
