You can use Cocoknits colorful opening stitch markers to mark rounds, repeats, increases, and decreases. Just place them on your needle between stitches or pin them into your knitting.

Made of steel, they fit up to a size US 11 needle. Each set contains 60 markers, 10 each of 6 colors. Use them with the Maker's Keep to stay organized! Packaged in a sturdy recycled cardboard round container.

Please note that the opening stitch markers are painted, not nylon coated, in order to keep them delicate and to prevent them from leaving ladders in your knitting. With extended use the paint may begin to wear off giving them a rustic look, but enough paint should remain on the marker to distinguish each of the colors.
