I started a new sweater project last night: the classic Double-Breasted Seed Stitch Jacket designed by Elinor Brown (the pattern is free!). So far, it’s been a pretty straight-forward seed stitch rectangle, but I’m about to divide for the fronts and sleeves, which will require some counting.
StitchMinder is an iPhone application that lets you count completed rows, pattern rows, pattern repeats, and increase rows, with just a quick tap to keep score. It’s pretty basic, but that’s what makes it useful (and better than tally marks). You could probably touch the row count with your pinky without ever putting down your project!
