I made these from the June apple socks pattern in issue 12 of Yarn Forward magazine, and easyknits biffle in a colourway called Ruby Slipper. (To any non-knitter who may be wondering why I'd spend time knitting socks when I can buy a pack of three from Asda for less than a fiver, if you'd ever enjoyed the superb comfort of a pair of hand-knit socks on your feet, I wouldn't have to explain!)
I also knitted a couple of valentine hearts for the girls in the family using left over sock yarn. These have lavender inside, so are suitable for scenting wardrobes or drawers. I used a very clever pattern by Vikki Harding (note: Ravelry log-in required to access link), in which hardly any seaming is required - only a few stitches, and a little grafting at each top.
