(I used a mushroom, pepper, carrot and cucumber.)

As I was making the prints above, I thought I'd capture my art table - After clean paper last week, there's now paint on it - no longer pristine.
I tried to do some maple key prints but just succeeded in making s mess. I've done it before and been more successful. Will have to try it again with different paints.
