Product Review (submitted on August 15, 2012):
Such a simple concept but these work really well. They keep your yarn so nice. I didn't seem to need to tug at the yarn to keep it coming. My big black dog decided to roll around on the yarn and afghan I was working on and it didn't tangle the yarn or create a big mess. They are a little pricey but I still highly recommend them. If they were cheaper, I would buy them for everyone I know that knits or crochets.
