1 spool of Stretch Magic cord. .8mm elastic diameter. 16' feet per spool. Clear.This fabulous stretchy cord is our go-to for stringing stretchy bracelets. The smaller .8mm thickness will go through smaller beads like crystals and pearls, plus this elastic cord features a long-life stretch. You can even use this stretchy cord for finger rings!How To Use: After stringing the beads, tie both ends of the stretchy together in 3-4 overhand knots tightly. It's important to leave a little give in the beads so that the bracelet drapes nicely on the wrist, but the knots should be very tight. Once knotted, dab a tiny bit of Super New Glue or GS-Hypo Cement on the knots to secure them. Trim the elastic tails with wire cutters or scissors. If desired, hide the elastic knot with a crimp cover or tuck the knot into a larger hole bead next to it.
