Debbie B, I used Steam a Seam 2. You can't tell from the picture, but there is a really tiny amount of fraying on some of the edges. The leaves are cut from hand-dyed fabric though, and I recently read that hand-dyed is a much tighter weave than commercial fabrics so the fraying is much less. Here is a link to a blog that talks about this issue:
