You're knitting what?!

A sweater! Can you believe it? This one. So far I have two sleeves. Trust me, the other one looks exactly the same.
The yarn is Green Mountain Spinnery Mountain Mohair in the colour Mesa. After turning Norma's Marta into this pile of yarngetti on the drive down to the New Hampshire Sheep and Wool Festival, I just had to have some for myself.

I started with the sleeves so that I could ponder what to do about the button bands on the main body of the sweater. As written, the pattern has you keep 8 stitches at each edge in garter stitch for the button bands. But the cabled portion of the sweater and the garter stitch yoke are knit on 5.5 mm needles and 5 mm needles respectively. And the garter stitch row gauge is different from the reverse stockinette row gauge, of course, so I can't help but think that this will mean a button band that is all stretched out vertically on the lower portion, and a different width on the upper portion by virtue of the smaller needle size.
I think I will cast on 14 fewer stitches for the body and pick up and knit the button bands and collar afterward (no hood, please). What say you, oh knowledgeable ones?

That is SO funny.
The sleeve looks FAB. I love your idea about the button bands.
That is a gorgeous sweater, well knit on that sleeve!
As far as how you're going to carry on regarding those button bands... I'd check on Ravelry and see what other folks have done... or if they followed the pattern what they think and just to see their results. Otherwise, I don't see any problem with your idea...
Gorgeous yarn, love the colour you chose.
