Clover is well known for its myriad of knitting accessories and notions, and I'm a great fan of them. Clover's Locking Stitch Marker with a clip is a smart idea that's pretty simple, as many good ideas are. The pack includes six of the clippy stitch markers. Clover even supplies you with a perforated notepad, so you're good to go right off the bat. Write a note and clip it to the stitch marker and attach to a stitch - simple.
