I have strung many rosaries and rosary bracelets...it's my biggest seller and I hate doing them with the rosary turn. The wire I like to use is beadalon .024 nylon coated stainles steel 4-5 feet. You wil need 59 beads (53 hail mary and 6 our father), a center a crucifix crimp veads, seed beads or heishi beads, depending on what types of beads you are using, separator beads or crystals, you have to be creative. I like to use tiger eye 4mm or 6mm and I like to use swarovski round crytals for the our father's.
www.rosaryshop.com has a pattern for making flexwire rosaries and wire rosaries. I hope this helps.
