Yes I know that you can’t put a light inside a pumpkin unless you carve it. Yes I know carving is traditional. But if you have small children and they want to join in, handing them a sharp knife with images of Psycho rolling around in your head is not necessarily the best or safest idea.
Sharpies are easy to use, permanent and will not draw blood. You can use stencils or go freehand. Just remember to be bold with your designs so they stand out. Clean your pumpkin gently with a mild soap and let it dry completely before launching into your artistic endeavors. Go spooky or sweet and have fun.
