Beading Needles are just like sewing needles, but much thinner and have smaller eyes. They are specifically designed to be used with beads or pearls to fit through tiny holes. Beading Needles vary by size: #10 thickest - #16 thinnest. Most Beaders prefer size #10 & #12 beading needles. These needles are thin enough to go through size 11/0 seed beads and have big enough eye to accomodate thread size B or D - most popular size thread among the Bidders.
