I have a book on flower pounding -- that is one of those projects that sounded like a lot of fun to do but I never found the time to pursue. I believe you need fabric that is prepared for dyeing (maybe washed to remove the sizing?) I had some special fabric for the project but I'm sure it has found its way into my regular stash! I quess one thing that put me off was the fact that the project probably can't be washed and I don't make a lot of wall hangings.
