I just got one in a swap with Majic Mama and it's great. I asked her how to make one too since I love it so much, you should pm her to ask where she got the info.

One way to do it is to make a small cut in a tennis ball, put the bell inside and then just do your felting over the tennis ball. It also saves on the amount of wool as you can make a good sized ball but not use all the wool it would take to make one that big.

I like teh tennis ball idea!

So how do you felt wool and what do you start with?
