Design it Yourself Sweater Project | Step 7

After estimating the amount of yarn I'll be using for my sweater (and making sure I actually have enough yarn) there's one last bit of math I need to do before before I start knitting. I need to convert the finished sweater measurements into stitches or rows.

Why I convert every dimension into sts/rows/rnds

The short answer

Gauge before blocking usually does not equal gauge after blocking. Knit fabric almost always changes when it's washed and dried. Therefor, the size of the knit fabric on my needles will likely not be the same as the final dimensions of my project.
