They turned out like this. I was worried because you could still see the yarn lines, but luckily they were felted perfectly!
I use three balls each time I use the dryer, and it makes our fabric SO soft. It's amazing. But I am used to air dried towels which are crunchy. I haven't decided what I'm going to do with the small ones. I thought they'd shrink a lot more so they are bigger than I thought they'd be. I'm thinking of combining them with some wooden beads and hang them up or make a wreath with them.
