Counting increase or decrease rows:
I went on vacation and didn't bring my counting stitch marker (the barrel kind with turning numbers). I used a piece of yarn in contrast color, and laid it between stitches on the increase round. It was easy to count how many bars were above the scrap yarn, and I moved the yarn from back to front (or front to back) on each increase round.
I actually like this better than my row counter, because I can see at a glance how many increases I've done (seven). This is the sleeve of my second Stopover.
