Birdie Bird Batting is a game-changing batting that you'll want to have in your craft room. This low-loft batting features a layer of 100% cotton batting stitched to a layer of 100% cotton flannel. The adherent quality of the flannel eliminates the need for pinning or basting. Simply lay the batting flannel side down over your backing fabric and smooth out any wrinkles with your hands, then place your quilt top over the batting and smooth.
