a row counter that is on a ring that you can put on your thumb and just tap to count your rows.
I have been knitting a sweater in the round and think this would be the most idea solution. I have a row counter that where you must dail after ever row. I looked at other row counters and even tried to use tally marks, but all required me to stop knitting. Just a quick movement with other thumb and off to the next row . . .
What other cool things do you think someone should invent to make our knitting lives better?
