Granny Squares are really nothing new. However, there are many modern versions and unexpected uses of the classic pattern. This Granny Square Kinder Surprise Rattle for babies is one of them.

This pattern is similar to the classic Grannys but consists of half double crochet (hdc) meshes.

There’s a German pattern too: http://www.mycrochetprojects.com/crochet/granny-square-ha...
