Stumped

So I have two window frames about 1.5' by 1.5' with dark brown paint and a copper handle on one fo them. They would look great on a wall together, but I am stumped. My muse is on vacation apparently and I have no idea what to put in them.

I've done pears, houses, birds, flowers and trees and wanted to try something different.

Here are my ideas......just kidding. I have none. Zip. Nada. Zero.

So lets hear them.....let er' rip.
