I use two different kinds of row counters. I use my needle row counter, with a few beads to make something similar to the picture below, as well as making an abakus type row counter
Nice! I have a Clover clicker, but that only goes up to row 99. On the upside, it doesn't run out of battery...and it makes just the most satisfying noise when increasing the count.
you can also make a row counter out off stitch markers. make a little chain by putting them together. works best if not to long. i use one for decreses in sleeves and sometimes for cables
