I love this pumpkin. This was one of those human ingenuity moments that resulted from necessity: the necessity to not carve a pumpkin due to baby in one arm. Also, I had a super cool white pumpkin since the store ran out of orange ones, so I wanted to do something different.
How to achieve these results? I used the white pumpkin, a black sharpie to draw the face, and black-light face paint to accentuate the face. Then, stuck thing under a black light. I also tacked on some glow-in-the-dark spider webs as hair. Again, baby was in one arm–so I spent about ten minute free-handing this–hopefully you can take it further!
