The clogs are then washed in hot water in a washing machine with a little soap - the felting usually shows up after about ten minutes of washing. Then the gift recipient takes the funny, slippery, soapy blobs of yarn out of the machine and sees for the first time that they might have received a real gift. Then, the clogs are checked every few minutes to see if they have reached the perfect custom fit.
The washing machine shouldn't be allowed to go into a spin cycle or the shape might be stretched out. The soap can be rinsed out of the clogs in cold water - something you wouldn't do if you weren't felting.
The clogs can be rolled in a towel to help with drying.
Then the clogs should be carefully shaped - when they are left to dry, they will retain the dried shape. I found that the yarn I used tended to become fuzzy and the fuzz could be patted down at this point.
Plastic bags inserted in the toes help to retain the "cloggy" shape while the clogs dry.
