1x Beadalon Supplemax Illusion Cord (0.3mm by 50 metres). Soft and flexible 'invisible' cord, for use in floating and illusion designs as it can be knotted to hold the beads in place (or you can use glue or discreet crimp tubes). Best used with acrylic, wood or non-abrasive beads to protect your cord from potential damage. This size jewellery and beading cord will thread through seed beads and 4mm crystal bicones (watch out for sharp edges on crystals, try adding a seed bead either side of the hole for protection of the cord). 0.3mm diameter or 0.12 inch.
