When finishing the second blue sock, I remembered to take pictures of the process of knitting an afterthought heel in order to follow up on the first post I did on this subject. I've decided that these are my favorite heels. I've been trying to clean out closets a bit in anticipation of having to put my house on the market and, you know, moving, and found the first pair of socks I made. They're ridiculous Lion Brand thick yarn knee high socks that I'd never really wear... and as if to prove it, I never wove in the ends. But I pulled them on just to see, and realized that, indeed, the gusseted heel is just not that comfortable on my foot.
After that point, you just keep on knitting the foot, eventually decreasing the toe in whichever style you want. This is a German toe, according to C, my sock guru. About three inches from the tip of your toe, you start decreasing at four points along the sides; you start decreasing every 4 rows, then 3, then 2, then every row, and gather the last few together at the top, which makes a kind of cute star effect there.
So, then, the heel. You can just start unraveling the waste yarn and pick up stitches on both sides as you go, but I prefer this method. Basically, take a double pointed needle (one a size or two smaller than your working needle makes this a bit easier) and start picking up the stitches on either side of the waste yarn. It's easiest to pick up all along one side first, and then the second side.
The one thing to be careful about is to pick up one loop in each stitch, and preferably the same loop (front or back) in each stitch. When you look at the stitches, they make a little V (or upside down V, depending on how you look at it). You want to pick up always either the \ or the /. You can tell you've done this because, a) you've got the right number of stitches, and b) they lean the same way all along the needle: /////////// or \\\\\\\\\\\\\\\.
(I should say here that there's probably a way to tell whether you should pick up the / or the \ stitches in order to make sure your stitches are on your needles properly, but I generally don't worry about that and just knit through the front or back as necessary... more in a sec.)
So when you're done with this, you've got stitches picked up onto two needles, with the waste yarn between. (And don't worry if you've got one extra stitch on one needle... that happens.)
The next step is to start knitting in the round on these stitches with the yarn for the heel (a benefit cited for this kind of heel is that if you run out of your major yarn, you can always just have a contrast color heel). If you're using double pointed needles, you'll probably want to spread the stitches out onto them before starting; with the magic loop, I just knit off the two DPNs.
There are, however, two things to keep in mind.
First, you'll note that there's kind of a wide gap on both sides between the two needles. Wider than you'd expect, considering it's the gap of one row of stitches.
What it means is that you have to pick up a few stitches in that gap to avoid little holes on the sides of your heels. Do that as you're knitting on the new yarn for the heel; I've basically taken to picking up two stitches at each end of each needle. It sort of seems like a lot, but that's what works best for me. Your experience may vary. Then, in the next couple of rounds, you decrease those stitches.
Second, the stitches on the DPNs may have been picked up twisted (I almost always seem to do that, which means I should probably be able to figure out what I'm doing and stop that). Just be sure to knit into the yarn coming off the stitch you just knit, whether that's the front or the back loop. I have to admit, I figured this out kind of by accident way back when, as I realized that doing that's just easier, or looser, or something.
Basically, after you've decreased the picked up stitches, knit a round or two without decreases (unless it's a loose fitting sock, as the Norwegian stockings were; then, for me, at least, the heel would have been uncomfortably loose).
Then make, essentially, a toe. Decrease at both ends of both sides every other row until it covers your heel (there should be 1 1/2-2 inches of stitches left on the needles, maybe). Kitchener them off.
If it feels too loose, decrease in more rows (start off every other row then switch to every row, or do 2 out of 3, or something); if too tight, decrease in fewer rows (every third, then every other...). Obviously that means you'll have to frog back, but it's all so simple that that won't take long.
