On an 80cm length of brass wire, thread 18 faceted 4mm beads (here in Siam Gold). Using a brass wire will help shape the knot.
Pass the 2 ends of the wire through a 14mm Rivoli Swarovski rhinestone setting (here in Topaz-Amber): the short end should measure 12 to 15cm.
With the long end, form the same symmetrical loop and re-cross the setting.
