One of my favorite things about knitting is the infinite variety of ways in which garments can be constructed. Socks are especially fun to experiment with, because if a particular method of construction turns out to be less than fun or doesn't fit well, it's not a huge investment of time and energy.
For my brother's Christmas socks, I decided to try something new: a resoleable sock, specifically, the Two-Yarn Resoleable Socks from the Interweave "Favorite Socks" book. Happily, the pattern was written for worsted-weight yarn, which I wanted to use anyway -- my brother lives in San Francisco and likes to go snowboarding in Tahoe in the winter, so he can put thick warm house socks to good use.
So far, I've almost completed the top of the first sock. When that's done, I'll be using the contrast-color yarn to pick up a looooot of stitches to knit the heel, sole, and toe. I just hope the leg of the sock will be big enough to fit my brother (who has what are affectionately known as "cankles" -- ankles not much smaller than his calves) I also hope that he will wear these enough that they will actually, at some point, need to be re-soled!
