I love to knit socks. They're portable, there's an infinite variety of patterns and styles to make, and a ball of sock yarn is much more affordable than buying enough yarn to make a sweater.
The problem is that when I finish a pair of socks, I always have yarn leftover. Not enough yarn for another pair of socks, but too much for me to just chuck it. I asked one of my knitting pals what I should do with the leftover yarn and she suggested knitting a bunch of squares out of it, and then, when I had enough squares, sewing them up into a blanket. Meh, no.
Then she suggested baby booties. And a few days later, I spied on Janet's blog two pairs of the most adorable baby booties ever. I found the pattern and whipped out a pair. Now I just need to find someone that's having a girl.
