I knit socks, wool, mostly for myself. I live in a big drafty house and my feet don't get along well with shoes, so heavy socks and tevas are my winter foot coverings. Each sock takes about 8 hours to make, so there's always an end in sight. Using four or five needles isn't hard, and turning the heel is a bit of a miracle. ;-) I mix yarns, adding cotton or silk to the foot part so they are sturdy. I'll be off to the two semi-local weaving shops soon to look for yarns - I don't need a lot of each yarn and mixing weights and fibers means I can buy leftovers for relatively little money. My knitting is easy to carry with me, but I haven't found a knitting circle.
