Stretch Magic Elastic Cord
Stretch Magic is a strong, clear, and opaque elastic cord for jewelry making, available in several different styles. The secret is a high-tech polymer that does not crack or become hard over time. Because the ends do not fray, it is easy to string. All you have to do is choose the right cord for your beads' hole size and for supporting the overall weight of your project. Stretch the cord before adding beads to prevent your designs from stretching out later.
