I saw a card made by Mary Fish using squares of cardstock that had shapes punched out. Then
I saw one similar to this made by one of her downline (not sure of her name) that was inspired
by Mary's card.
I have been using up bits and pieces on my desk, so pulled out all of my circles. I had to punch a few more, but had a good start. My colors are bermuda bay, so saffron, cherry cobbler, and calypso coral on a very vanilla base. I even had a so saffron brad to use. Give this a try with any shapes you have laying around. You could try mixing shapes as well.
