Found art

If we had skis it would be wonderful to be outside in this deep powdery snow.

But since we don't, I am staying inside and moving things around and straightening up.

I moved all the cans and sacks and boxes of things out of the pantry.

Underneath where they had been I found this design on the shelf.It is pressed flat into the wood.

Isn't it a lovely pattern?

What do you think it used to be?
