Does anyone use Lee Valley's beading tool? I bought one a while back, and I've tried using it a few times, but I can't get the hang of it. I'm not ready to give up on it yet. Sometimes it takes me quite a bit of practice to figure out how to use a tool (card scrapers being one of the best examples), and then I'll wonder why I didn't get it right the first time. Anyway, does anyone use this tool? If so, for what in particular? And do you have any tips?
