Bead tips and clamshells are used to join thread to a clasp, and are easy to use. They're great for use with silk because they make strong, streamlined finished jewelry.
You can string this bead tip onto the end of your knotted silk cord to hide the knot at the end and provide a loop for attaching a clasp.
Clamshell style crimp beads are surprisingly versatile in jewelry making. Perfect for making earrings, necklaces, bracelets and much more, just string one of these beads on an almost-finished project, knot your cord or thread, and gently clamp these beads over the knot to hide it and reinforce it.
