Stitch markers, or row counters?
Row counters are what she described. I don't use them much and usually wish I had :mrgreen:
Stitch markers are little circles you can slip onto your needles to mark where a pattern begins, or so many stitches for something, or where you're going to put stitches on or take them off for a sleeve or whatever. They're handy when you start, because you can put one on every ten stitches or whatever and you know if you've gained or lost any stitches you shouldn't have. They slip from one needle to the other while you're knitting and you take them off on the last row before you bind off.
