Knitting calculator adjusts the # of stitches or rows in your pattern so it fits! Stop wasting time and money knitting projects that don't fit. Use the Knit Fits! calculator to adjust your knitting pattern for a perfect fit. Use it frequently as you knit your pattern: to calculate how many stitches to cast on, to count the stitches in an increase or decrease, to adjust the fit of certain rows in the pattern (ex: bust or waist measurements), to know how many rows to make for the right length. So smart it can even handle special situations such as multiples of a certain number of stitches for designs that repeat. Easy and convenient to use...the calculator stores the pattern's original knitting gauge and your own knitting gauge for you so you only need to enter them once. No more confusion, no more guessing, and best of all, no more undoing hours worth of work to start over!
