An old shirt, seashells and an idea

People often say they want to be an artist but can't afford art supplies. I say all you need is time and imagination.

I borrowed this shirt and laid out some shells that had been given to me years ago. I'll bet you're wondering why...

I thought this would make a cute Christmas card design for the people who gave me the shells and for my friends that go south in the winter. What do you think?
