This set fixes the quandry: How can I see my stitches? This is def a thing - knitting with dark yarn on dark needles makes it super hard to see where the stitch is, especially for us older gals with (ssssh) eyesight that is, shall we say, not up to par? Same with light on light! This set helps with both - Just swivel the needle to bring up a natural/light background or twist to the dark side if you're knitting with lighter yarns. It all becomes clear!
