Jack-o'-Lantern of Lights
This year I thought I'd try something different. Instead of putting the light inside the jack-o'-lantern I thought I'd make the lights part of the jack-o'-lantern. It's fairly easy to do and requires much less dexterity than wielding a knife to carve features into a pumpkin.
You will need:
Pumpkin for carving into your jack-o'-lantern
Sets of Electric Lights. I used 20 light, 120Vac light sets that were 5ft total length. (Dollar Tree) The number of sets of lights you need depends on the size of your pumpkin and the amount of detail you want to illuminate. I used two sets (34 lights of the 40). You could use a battery-powered LED light string, if you don't have 120Vac nearby. I tried both orange and purple lights.
Electric drill and 5/16" drill bit. That's the size of drill bit that worked for me and the lights I was using.
