I bought a cheap twin size mattress cover to use on my big board DH made me last weekend. I 1st covered in in 2 layers of inexpensive batting from Wally world them the mattress cover and finally some muslin. It's wonderful. While DH was stapling all the layers underneath it I was running my hands all over the top, around & around the big board. I'm so proud of him for making it. Usually he can't put a nail in a piece of wood lol but this project turned out perfect!
