Clover is well known for its myriad of knitting accessories and notions, and I'm a great fan of them. You'll never lose your place again with Clover's Pattern Chart Market set. Use the chart markers to keep your spot on any knitting, crochet or sewing pattern with the power of magnetism. I duel purpose it and use it as a bookmark, super handy. The set contains one 30cm (12") marker, as well as a 22cm (9") magnetic marker.
