Know Your Beading Thread


Thread


Beading thread tends to be pliable and soft, great for knotting, looming and working with seed beads. Most jewelry-making threads require a needle. In needle sizes, larger numbers indicate finer needles. To figure out the jewelry needle you'll need, view our ''Beading Needles: A Comprehensive Guide for Every Project'' article.
