I'm using flannel and fleece combo on some of the baby quilts I've been making - I've never pinned so much in my life! It "moves" easily as it has a high loft and even just the flannel/flannel one I made - required so much pinning to keep it from moving also - also a high loft flannel. But, it is making up some lovely little baby quilts! I have used flannel on my grandson's twin sized quilt for his bed. I pieced the quilt top and used flannel on the backside for cuddly warmth! and he loves it - and It was not bad to work with - just use those handy pins! Ordinarily I don't use pins; I can ususally handle just laying fronts and back together and get a very nice seam, but not with using the loftier fabrics.
