The Art Card Window

I recently made a card-stock piece with a rectangular hole cut out, so I can view old, busy, unfinished works to turn into art cards.  Then I just mark the image with a pencil.  
Look!  I have 10 new starts of Art cards and they are all originals!
And the scrap from around them can be used in collage and Mail art!
Recycling never looked so good!  If you know how to see the smaller images larger, you will notice that I have "outlined" ten potential new art cards on the 3 images!!

the "art card window" in action!
