8/29 finished and blocking. I made a few modifications:

1- I did not like the beginning garter tab in a seperate color from the next section. Looked too disjointed. I did my garter tab bi-color in color b and c and the set up rows accordingly. Happy with how that looks.
2-slipped the first stitch of every row and knit through the back of the last stitch of every row.

Did run out of color b 5 yards from the end, but only because I was planning on doing the small and decided to do the medium. Had another yarn from a verb for keeping warm in a close colorway so finished off with that.
