I got my cardboard from Joanns. They throw them away and I asked if I could have them so when ever I go there I ask for some. I can cut them and get a lot of them and I gave my sister some and she has a head start on hers. she did a lotr of her fabrics when I was staying wiht her a week ago or so. It's a good idea nad it also keeps your fabric looking nice too. Have a great day, Huggies, Fay
