It can happen to anyone… the late discovery of a yarn over hole. In my case, I found it after many rows of decreasing and couldn’t bear the thought of frogging so many hours of knitting. Using all of my resources (books, knitting heroes, and the internet), I found an excellent solution to share with you:
“To close a yarn over, use a piece of matching yarn, threaded in a yarn needle, to encircle the hole on the inside of the garment and gently pull it closed. Weave in and trim both the ends.” –Margaret Radcliffe
It worked like a charm and I would defy you to find the hole (from the front).
