I used batting and canvas, stretched it as tight as we could and then spritzed with water several times to let the fabric shrink tight around the board. My big one has been in use for at least 8-10 years...isnt as pretty but not too bad. I also made one smaller for classes and travel. Sprayed adhesive spray on it thinking it was starch...duh! Made it somewhat of a mess but it still works fine. I made a muslin pillow case to cover it so it did not look so bad when I take it to class. When it gets yucky, I just wash it or sew another one. I also covered the board in a heavy duty plastic bag so the moisture from steam does not cause the wood to warp.
