20% wool - 80% rayon felt in black. I pre-felt the fabric for you, so it arrives ready to be used in your next project. This process enhances the texture of the felt, making for a finer finished product. I cut and roll the felt rather than fold to eliminate creasing. Following the felting process, the fat 1/4's final measurements average to be 17 1/2 inches square.
This is the same felt that I use in all of my finished handmades and kits available from my Etsy store.
