The Rainbow Twist Markers have metal rings that smoothly slide over US 10 needles. This is a set of 8 markers, which can accommodate larger projects. They are 2 inches long.
I love to knit, but often I lose track of my location. I'll knit right past the stitch change, and have to back up and fix the mistake. I turned to commercial stitch markers, but they were too small to be effective, or were easily lost. Once I began using my custom made stitch markers, I not only complete every stitch change, but now I get compliments everywhere I take my project to knit!
