Thread Sizing Guide

Deciding what type of cord or thread can be a challenge. As a general guide, if your beads are a soft material bead such as pearls or amber then a silk, polyester or nylon thread will do. If your beads are a hard material such glass or stone then you might want to use a polyester or nylon beading thread. For metal beads, large beads, rough texture beads or large holed beads you might want to use a strong thread like Tiger Tail™.
