The Cocoknits Split Ring Stitch Marker is designed to be easy to use on the fly! A simple open loop with a pointed leg that will nestle into your stitches and stay while you're working - easy to remove and re-position while crocheting or knitting - creating increases, counting rows or repeats, or working cables. The steel construction is sturdy but flexible so the opening can be adjusted to accommodate the size of yarn or collection of stitches being marked. And they are nylon coated steel like our other stitch markers, so they cling to the Maker's Keep, Maker's Board kit or any magnet.
