These cute ring stitch markers by Tulip are indispensable helpers when knitting. You can slide a ring marker around the needle while knitting, between two stitches, to mark a specific spot, for example the beginning of a row when knitting in the round, before or after certain pattern stitches or to indicate a decrease or increase.
