WoolFelt® from National Nonwovens is one of my favorite fabrics for an embroidery base. Use the instructions from the Boiled Wool Felt® Tutorial to give your felt an aged look. If it isn't to your liking, just iron it flat again. You can further enhance the felt with tea, dye or a paint wash.
There are 166 colors available in 12" x 18" pieces--155 current colors and 11 discontinued colors that we still have in stock. Download and print your own FREE Color Card of this felt from National Nonwovens.
