roseanne, can you take a picture of what you are talking about and attach it to your post? i have not worked with the bead maker but i emailed a lady that had a cake on her website with a ribbon that had beading around the edges and she told me how she did it. she did say that there would be a line (could call it a ledge, a lip, etc.) left behind when you open it up. i'm assuming you are supposed to maybe use an exacto knife to carefully slice away the excess.
i wanted to buy one the other day but it was like $30 for the small bead maker. it was about an inch wide and maybe 8 inches long and 1/2 thick. so about the size of a harmonica i guess! like a rubber stamp that you kinda spread apart and lay your fondant rope in the middle and close it up which in turn forms your bead strand. the one i looked at didn't really open full-face so i could definately see the problem of having to take the bead strand out of the bead maker before you can start trimming on it because they are still soft and smushy. i hope someone can help you with this because it would really help me out as well!
