You can use this for any season... right now, we did it with leaves.
Find a simple clip art picture of the object you want. I've attached the leaf one that I used for this one. For winter we do really cute mittens. Paste the clipart to Word, and blow it up big. Then cut out one copy of it and glue it on black paper. Copy on the black paper. So what you'll have is a white object framed all in black.
(Note: The one I'm attaching is done for you b/c I did it in Paint so that the black is already on the page)
Copy enough for your kids. Have them decorate the object and the white frame around it if you've allowed for a frame with MARKER. Has to be marker.
Then they paint baby oil on...
