A bookweight is used to hold open recalcitrant books that refuse to stay at the page you want. I use my bookweight a lot on cookbooks and knitting books. This project is good for using up scraps of feltable wool. It also makes a quick, unique, and useful gift. If you want to learn how to use double-pointed needles, making a bookweight is like making a sock that has no heel or toe, or a mitten with no thumb.
