You can easily make lasting designs with Elasticity 0.8mm clear cord. This soft, crystal clear bead cord from Beadalon stretches like a rubber band. It's perfect for bracelets and hair bands. The smooth, clean finish slides through hair without grabbing like other elastic products. Bracelets made with Elasticity will not stretch out like those made on elastic thread and string. Elasticity is easy to tie, too. We recommend using a surgeon's knot to secure your designs. To secure knots, use a flexible adhesive. This spool offers 100 meters of cord.
Best elastic beading cord
This is the best elastic I have found. It is the least likely to break with stretching. Some others if you hold each end and pull as hard as you can it will break, this doesn't, at least with my limited strength. It is easy to work with and knots well.
