We're sad that we just discovered this idea on the Etsy blog today. Between last-minute costume stitchery and related Halloween fooferaw, we haven't got a spare minute. But if you do, perhaps you'd like to spend it making the coolest, scariest jack o' lantern ever.
Designed by Tom Nardone, author of Extreme Pumpkins, this design actually isn't intimidatingly complex, but still gives great bang for the buck. All you need is a big pumpkin, a small pumpkin, and the usual carving accoutrements.
