Besides being a painter, I love to crochet. It started as a way to occupy myself while trying to quit smoking and has blossomed into it's own beast.
I call them ArtRat Hats.
They are created without the use of a pattern and I choose the yarn and pattern as well as height based on the person who orders them. It's that opportunity to create a specific piece for someone's personality that makes them so much fun to make.
