I don't think that I would have appreciated the concept of yarn bowls so much if I didn't have cats. When I knit and yank the yarn it happens that the ball rolls down from the couch and over the floor, sending quiet signals to my two cats to come and play. And even if they leave it alone it always end up strands of cat hair in the yarn. Problem solved with a yarn bowl! Here are some to explore, all from Etsy, all handmade.
