I bought the brooch on eBay and the Swarovski pearls, rondelles, the clasp, and the wire at www.artbeads.com. Artbeads also has a video tutorial on how to use crimp beads and a crimper, which I got at Michael's.
WOW that is really pretty, looks very profesional . I could see myself attempting something like this and hurting myself terribly in the process - congrats on the great job .
