I made this super simple Christmas Counterdowner (they call it a "counterdowner" on a Christmas video Noah enjoys watching over and over and over and over) using a cheap, plastic frame as I figured this might be something Noah would want to help with and he'd do better with a plastic frame versus glass.
I made the image inside the frame in PSP and printed it out. I left a space big enough to write in the numbers with a dry erase marker. You can download the image here. It's for a 5 x 7 picture frame.
So easy I don't know if I should even call it a craft or not. Wait, I did use scissors to cut it out so that counts, right!
