I presented a row counter bracelet for knitting before, I find this row counter even better because you simply take it with you while knitting. It works like a stitch marker and every row you pick up the next ring.
You can easily improvise this from different coloured yarn loops or paper clips, e.g. 4 dark coloured, 1 light coloured for the five, again 4 dark coloured, and again 1 light coloured for the ten ;-)
