What I am using is the first formula that they came out with right after they lost the original supplier. I bought it last year at a show. Quite a few places online still stock this 'new' version. The adhesive is basically the same but the release paper is very waxy. Waxier than wax paper and it makes marking on it almost impossible. I have been primarily using it for my quilt labels. For that it works fine but I'm prepping a wool project and it is just not working.
