My very first quilt was flannel. Made it for my baby granddaughter. 3"squares. No prewashing (which I do now for flannel only). Didn't starch. Didn't use wider seams. Didn't press seams open. It is flannel front and back with warm and natural batting. It is over 10 years old and washed many times and she still uses it at almost 11 years old. Go for it!!
