The sock is steadily progressing now. I've been hard at it early mornings before work and late evenings after work. And I'm quite pleased with the result - but then, I'm an easy marker.
There's some uneveness in the stockinette of the bottom of the heel flap - tighter knit rows than purl rows are to blame. And the knitting is noticeably loose between the stitches of needles two and three. Some yarn-overs in the lace pattern aren't quite as distinct as others - I may not have pulled the yarn over knitwise on a few of them. And that's just for starters.
But I do believe it'll look like a sock when I'm done and not dissimilar from the pattern intended by the designer. Perhaps more importantly, I do believe that it will fit a human foot. All of which is better than it might have been.
