oh wow, thanks so much for posting this. I was thinking of Torey, she made my avi and does a great job, but this guy has a great thread, and so nice of him to do this. He must love it to post to do it for everyone!! I bet that keeps him busy. Bookmarked this so I'll be ready when I get my Reo. Took the first prep step today, got a couple cheap bf atties ordered. Not the ones I wanted, but at least I'll have something I can use til I can get something I like better. Next on the list, break into diy. Keep ploddin along one step at a time, and I'll get there!!
