Flexible, but strong, Hanging Line for Stained Glass is a great replacement for wire or fishing line. Use the connectors (sold separately as part #130351) to close the loop instead of trying to tie a knot. The connector is easy to crimp with pliers. Simply run the line through the connector, then through the stained glass hanging loop, back through the connector, and crimp with pliers. It’s a fast and easy way to secure your stained glass project without a knot that may come undone.
