ARRRRGH!

Work hell has abated for a while, after my 72-billable-hours week. Now I am in Xmas stocking hell. Someone help meeee!!!

I am using this pattern, courtesy of the ever-fabulous Wendy via my comments. I'm not doing the applique stuff - just using it as a basic framework, and I'm doing it in stripes. I figured working flat would be easier for me than in the round, since I'm not a sock maker and don't feel like figuring out everything when I'm doing a project for someone else under a slight time crunch.

So, I'm merrily knitting along and have a nice looooong piece of knitting, when I get to the Divide for Heel section. Let me call your attention to the previous direction, and then to the Divide for Heel direction:

Dec Row: K1, SSK, k to last 3 sts, k2 tog, k1—59 sts. Cont to work in St st, rep dec row every 10th row 3 times—53 sts rem. Work even until piece measures 13-1/2" from turning ridge, ending with a WS row.

Divide for Heel
(RS) K13 and sl to holder for right half of heel; k17 and sl to 2nd holder for instep; k13 for left half of heel. Work on these 13 sts only.

OK, so if I have 53 stitches remaining (which I do), and I slip 13 of those to a holder, then another 17, that's 30 stitches slipped to a holder - which leaves 23 stitches remaining. But you'll see that the last piece of that says I have 13 stitches and I'm working on those 13 stitches only.

Um, what happened to the other 10 stitches? Yes, that's right - they're SITTING ON MY NEEDLE MAKING ME CRAZY! Am I crazy? Am I reading something wrong? Is there an egregious error in this pattern? How do I fix it? (Assuming the answer is not that I am crazy)

Heeeeeelp meeeeee wonderful knitting-blog-readers!!!
