Oster and I made these in about 5 minutes yesterday.
1. find a leaf that looks like a pumpkin, the more alive it is the better (dry leaves just fall apart)
2. fold leaf in half tear out an eye hole, nose and mouth (see pic above)
3. glue leaf to a card and you can also put a heavy book on top to help it stick.
that's it...it was super fun trying to find pumpkin leaves!
