It was a little frightening watching the blanket get smaller and smaller, I'll admit. It started out at 56" or so and then shrunk after only four minutes in the washing machine. Okay, I set it on hot but when I checked the water, it was lukewarm at best.
So, I took it out and rinsed it in cold, then smooshed the excess water out and put it in a dryer for a light dry. Six minutes later I called it done. The weave had filled in completely. It measured 36". So, talk about shrinking.
If I had used two strands of yarn instead of one, there wouldn't have been so much space in this weave, and I probably would have lost only about 10" instead of 20". But, it makes a very nice wool lap blanket, the kind to sit on the couch with or put on the foot of a bed for a little added warmth. It was really satisfying to make something bigger than a shawl or a scarf.
