I am planning a baby quilt to be made up of flannel snowballs -- fussy cut centers of monkeys piloting airplanes with corner triangles of orange, yellow. red and blue. I want 6 inch finished blocks -- if I was using cotton, I would cut my center square to 6.5 inches and the blocks to make the corner triangles to 2.5 inches. Since flannel ravels, how big should I cut my pieces?
TIA
