Reposted for test knits to identify/fix problem with border count. Please note that I am a full-time graduate student and am unfortunately not able to help knitters with this pattern.

Jints suggested this might be the solution:

Border solution for odd stitch.
I have completed this blanket several times and I corrected the stitch count problem in border by transfering the odd extra stitch to be part of corner, so you will work 2 stitches in corner instead of one.
i.e.
R1; Kfb, p116 sts, kfb, PM, p2 (in corner) repeat.
R2; Eyelet row: yo, k2tog until marker, yo k2 (in corner) repeat.
for spindle cables,
R5: Yo (p2, K2) 30 times, p2, yo, K2. repeat.

Continue like this making changes as you come to them. so stitches one side of corner mirror those on other side of corner.

Much appreciation also to mrmobo also took the time to propose a solution here: https://www.ravelry.com/projects/mrmobo/sleeping-beauty-b...
