If you've ever had to cast on hundreds of stitches for a blanket or a sweater and lost track halfway through, you need these numbered stitch markers in your life! Comes in a set of 6: three 100 markers and 1 each of 25, 50 and 75. Available on rings or removable bulb-shaped safety pins. Product Details: * Material: Birch with stainless steel rings or metal removable pins * Approximate Size: 3/4” x 3/4” x 1/8” There are two options for ring type: * Rings - stainless steel rings with a 9.5mm inner diameter. These are big enough to fit over size 11 needles, but not so big that they're uncomfortable to use on smaller knitting. * Pins - removable black bulb shaped safety pins, which fit best on needles smaller than size 3.
