Will it Felt?

I have wanted to make my own dryer balls for quite sometime, but I do not generally use wool as a rule. I was given some Patons Classic Wool and this was the first thing to pop into my mind. You generally need 100% wool for it to be able to felt and this fit that description, however it had been treated to be machine washable. So I did a little research and found that it may be possible to felt washable wool if you use a high enough temperature water while felting, then cross your fingers that it works.

Step 1. Wind your balls of wool yarn. (I made mine about the size of a baseball.)

Step 2. Use a yarn needle to weave end of yarn into the ball.

Step 3. Put yarn in a sock and put it in the washer with a load of clothes and hot water. (Top load only as it will agitate the yarn the best). When the wash cycle completes put it in the dryer also on high heat. When cycle is complete remove balls from the socks you put them in. 

 The picture above is after the yarn had been felted...so the answer to my question "Will washable wool felt?" is Maybe, but not very likely. The darker yarn began to felt and has continued to felt as I use it. The other two balls still work for their purpose, but if I do this again in the future I will definately use wool that has not been chemically treated.
