I've finished knitting my second pair of plain, toe up socks. I don't think that I've quite gotten the hang of doing a short row heel, and I'm not sure I ever will, I find them a bit fiddly. The good part is, once you're done the heel, there's no more fussing with increases or decreases, just plain knitting. In a fun and cheerful yarn sometimes that's all I feel like doing, knitting endless spirals of stockinette.
To be perfectly honest, though these are cute socks, the real reason I bought this yarn is because I thought that the leftovers, paired with a bright colourway like Peacock or Lemongrass, would make a really fun striped baby surprise jacket, like this one!
