Calling all of you sock knitters and lace knitters! Cocoknits now has x-small triangle stitch markers. The little envelope contains two sizes of stitch markers. The smallest fit up to a US 1 (2.25mm) and the "larger" size fit up to a US 3 (3.25mm). The black and white color combo make the markers easy to see whether you are knitting a light or dark fabric. Love these!
