I had a hole in one of my very favourite pairs of socks. They are Monkey by Cookie A. which nearly all of us have knit at least once. I think I've made at least 3 pairs. But this pair is MINE. I knit them toe up in Koigu and I love love love them. I probably wear them at least once a week. So, the hole was devastating!
I keep small amounts of all my sock yarns for just such an occasion in a ziplock bag in my stash, so I dug that out and then picked up the stitches above and below the hole on two small needles. I think I used my 000's. Then I grafted them together just as if I was kitchenering a toe of a sock. Then, I reinforced the areas around the hole with the ends. I wove them through the rows following the stitches themselves in the places where the yarn looked a bit worn. Then I weaved the ends inside the sock. It took all of 5 minutes, and look!
Don't procrastinate like me! Today's lesson: a fixed sock is a wearable sock! :)
