Well, I did until the wee hours of this morning, suffered another bookmark purge by the computer. Found my way back here and so far, that's about it. Try searching for(posted 9671 days ago)free knitting pattern socks
on something like Ask Jeeves.
I've also, somewhere, got a magazine with the pattern in it, but first I'd have to find it, and then I'd have to knit it and re-write it because it was a terrible pattern. It is, however, seamed all the way down the center back, I've never seen a foot quite like yours with a flat top, not that I've seen every pattern out there.
In the meantime, if you can knit on double pointed needles at all, start the top of the sock on 2 needles and after an inch, or at least before you get to the heel, change onto double points-I'll admit, I do almost all my circular knitting flat for a few rows to an inch or so. Never have a twisting problem that way.
When I get over sulking about my bookmarks, I'll see what I've got handy in print patterns. I don't suppose you can remember anything about where you came across this pattern, can you? Gerbil
