I've been using Accu-Flex® wire in my necklace and bracelet projects, but I'd like to explore other stringing materials. In particular, I'd like to know how to select the appropriate weight of FireLine® and how to finish off ends attractively and appropriately.
Berkeley® FireLine® thread for jewelry-making is a strong braided thread that works well for all types of beading techniques, including stringing. It will not stretch or fray, and resists abrasion. It comes in several different weights, however the 6-pound version is most popular for stringing as it is strong, not too thick to pass through the beads a few times (if the design calls for that) and remains flexible. A good rule to follow is to use heavier weight threads with heavier beads, and lighter weight threads with lighter beads.
To string with FireLine, use about two and a half times more thread than the length of your project. Cut the thread with Acculon® wire nippers to get a clean thread end. Pass the thread through a size 10 beading needle and slide the needle to the middle of the thread so you can work with doubled thread.
Wax the thread thoroughly. Pass the needle and thread through a 1/2 inch length of French wire and slide it to 1-inch from the thread end. String one half of your clasp and tie a square knot with the working and tail threads to loop the wire around the clasp. Pinch the working and tail threads together so they stick.
String your beads as desired, allowing the tail threads to tuck inside the first few beads if possible. When finished, string 1/2 inch of French wire, the other clasp half, and pass back through the last few beads strung. Tie an overhand knot around the thread between beads and pass through several more beads; repeat to secure the thread. Trim the working and tail threads close to the beads using a thread burner. To add extra security, add a dab of G-S Hypo cement adhesive directly to each knot.
