I'm new here and new to knitting, too. I've been wondering how one goes about keeping track of rows & stitches, and you all have given me some great ideas. (I like the PDA applications!)
I also ran across a little gadget at a local knitting shop that is a rather attractive bracelet that you use to count rows. You can see it here: http://www.mybagatelle.com/
Click on the "Counters" button on the left.
I'm not sure how to buy these doodads through the web site other than emailing her. They look pretty cool to me, though!
