Don't use felt!!! I used felt on my design wall since it came in a wide width and I didn't want a seam in my design wall. However, fabric does not stick to the felt as well as flannel. Joann's is now carrying a wide width of flannel, but it doesn't come in white or off white. That is why I didn't purchase it originally and went with the felt. Batting works great also, but my design wall rolls up on a roller (over my closet) and I was afraid it would stick to itself too much and not pull down well. My DH made my roller design wall from an outdoor roller shade and I attached the felt to it. Now I am taking the felt off and need to put something else on. Has anyone pieced the flannel for their design wall?
