I considered it a couple years ago, but it's use is somewhat limited. Quilting cotton doesn't felt well either as the embellishment or the base. You need a material with long fibers to be successful. Wool is the traditional material with wool roving used as the embellishment. I used to make a lot of knit felted bags which is why I was thinking about it. There are lots of YouTube videos. That would probably give you the best idea of its usage.
