With the KnitPro locking stitch markers you will keep track of your stitches while knitting and crocheting. These stitch markers can be inserted into or around a stitch, for example to mark the start or end of circular rounds or to mark the spot before or after a decrease or increase. They also come in handy for keeping track of the number of rows knitted or crocheted: place a stitch marker every 5 or 10 needles or rows, so you can see at a glance how much progress you made. They can be removed at any moment. One of the benefits of locking stitch markers is that they cannot fall out of your crochet or knitting work. Made with plastic. One pack contains 30 stitch markers in different colours.
