The kata square is a useful crochet project to make blankets, afghans, and throws. They are also beautiful enough to function in their own right as a doily or such item. The Kata square is an attractive and easy project you can work on just about anywhere and any time. Moreover, it can be very therapeutic and meditational for those moments that you simply need to wrap your head around things. Enjoy. A ink to the free pattern is at the end of the post.
