Thanks so much for your help! I think I get it...just to confirm, here is what I plan to do:
1. k1, ssk
2. k10, k2tog, ssk repeatedly until I count that I have 13 stitches left and then
3. k10, k2tog, k1.
I'll have 86 stitches total in this row.
Do I count the 86 as I go or at the end? And since there are 13 stitches in step 3 above and 2 stitches in step 1, does that mean there are 71 stitches in step 2?
