Victorian pumpkins. I find this idea charming.  Really.   I do.  Imagine someone from the Victorian era, like Elizabeth in Pride and Prejudice, making stenciled pumpkins.  Would Mr. Darcy gently take Elizabeth’s hand and guide it as she positioned the stencil and painted the pumpkin?  Would he look longingly and deeply into her eyes?  Would Miss Bingley stumble upon this intimate scene and spat out retorts to Elizabeth?  Probably. Anyway, for a style totally different than the cross-bones-and-skull pattern that is common among grandsons, you might want to try stenciling a pumpkin.
	Do you think the Bennett household would make these adorable and tasty mini ghost cupcakes? Somehow, I just can’t imagine Mrs. Bennett being so culinarily inclined. . .

Here are three more random ideas:
Halloween candy bouque. This is a delicious way to decorate (and use up some of the candy that might be floating around your house.  I think a granddaughter would love to make one of these to decorate her bedroom.

Cupcake sleeves. This site is selling the sleeves. However, I’m suggesting that after seeing them, you can create sleeves of your own with your grandchildren.

Halloween stencils. Another cupcake idea here. Again, this site is selling the stencils. All of you creative grandmas can make stencils out of card stock and then use them to sprinkle powdered sugar designs on your cupcakes.
