Well, it's off the needles and blocking. I still can't believe I made it. It really came out nice. I skipped the last few rows, as I couldn't take my husband asking how the "car cover" was going. Sigh. I also cheated and did the crochet cast off, rather than the complicated knitted one. I so hate knitting several stitches in one stitch--that's why no matter how much I like nupps, I don't do projects with them.
It came out to be just over 4' wide--plenty big for a lap blanket.
Also, here's a pic of the Shetland triangle kerchief in action:
