Add these silicone stoppers to your notions pouch and never lose stitches again. The hexagon shape means they won't roll away from you when not in use. Four stoppers per pack, in a useful re-usable tin.
For needle sizes 2.0mm - 2.75mm (US 0-2), place both needle tips into one stitch stopper. For 3.0mm - 10mm (US 3-15), you need one stitch stopper per needle. Approx 14 mm diameter.
