Just Made It

I'm designing a new cowl and mitt set.  The intent is for each (cowl and mitt set) to use a single 100g skein of worsted weight yarn.  I love not having lots of leftovers -- just enough for an emergency repair.

I recently finished the prototype cowl and had just enough left over -- not enough to knit another round!  Perfect.

Since the cowl features a border on both the top and bottom, I had to calculate how much yarn was needed for the border so I knew when to stop knitting the body.  My rule of thumb is as follows:

(diameter of needle x pi x number of stitches/row x number of rows x 150%) / 1000 = meters of yarn required
