Begin with a small wad of wool, then wrap lengths of wool tightly around it. Keep adding layers until your fluffy ball is approximately twice the size you want it to eventually become. Saturate the ball in the hot, soapy water, and then gently roll it from hand to hand without squeezing. Keep doing this for about 10 minutes, dipping it in the hot water as it cools. The wool will seem like a wet, scraggly mess, but don’t worry. Soon the ball will begin to harden.
