I chose the Hat-heel socks from the Fall 2009 Knitty since I've been wanting to try this construction out and I figured I could use up quite a few of my leftovers in the process.
I used up nearly all of the Patons Kroy sock yarn I still had left in the heels, as well as the Four Seasons Gründl Hot Socks Othello I have in that blue-green jaquard colorway for the foot and leg. The toe and tip of the cuff I knit in Bernat Sox Multi and still have a bunch leftover.
At first I thought the heel and gusset flaps/hat flaps would look funky in the finished sock, and, admittedly, they did take a bit of getting used to. The heel, though, is very comfortable and form fitting. I wish I'd taken a picture of the little basket of heel and flaps grafted together, but I forgot--it's really cute! My only annoyance with this pattern is the amount of ends I had to weave in, what with all the breaking and rejoining yarn on the heel, leg, and gussets. Of course, I had a few more ends than normal with the different yarns used, but still, many more ends to weave in than I tend to like for socks. That doesn't mean I won't use this pattern again, and I'm going to see if I can find a way to remedy all that end weaving, but otherwise, this is a very nifty way to make socks. I even learned the figure-8 cast on for the heel, though I think I'll see how the magic cast on works out on this heel next time. Might be less fiddly.
Next on the knitting agenda is to finish sewing the sleeves in the Point Gammon (at least I finished knitting those sleeves!), and to get cracking on the baby gifts for my SIL since her baby shower has just been announced .... and I've got til just after Thanksgiving to knock out a baby blanket and hoodie cardy. To keep me sane in all that baby knitting, I'm going to take part in another KAL, this time Woolly Wormhead's Mystery KAL. I've always wanted to do one of these!
