Actually, when you finish the steps that you've written out, you'll have 2, 12x6, and 12 sts for a total of 86sts
1. s1. k1, ssk 2
2. k10, k2tog, ssk repeatedly until I count that I have 13 stitches left and then 12x6
3. k10, k2tog, k1.12
It might help with the pattern in general if you use stitch markers (this cam be as easy as a loop of yarn) to mark off the repeats. Makes counting easier and also spotting any possible mistakes. Love to see the finished blanket!
