This came today from KnittingDaily, for curvy Waist Shaping:
This little wonder widget takes you through the steps of Waist Shaping and does the math for you! It asks you for all the pertinent information: stitch and row gauge, hip/waist/bust measurements, desired ease, and the necessary vertical measurements, then gives you stitch counts, row counts, and fills in the blanks for such things as "work decrease row every X row Y times."
