Hollow Out Pumpkin
Use a knife to carve a large circular opening into the bottom of your pumpkin. Clean out the inside thoroughly, scooping away the pulp and seeds with a spoon.
Transfer Your Pattern
Rough out a design on paper first, then mark the dots on the pumpkin with a permanent marker. Find a free template online, try a swirling or geometric design, or randomly space dots on the pumpkin shell.
Drill Holes In the Pumpkin
Gripping the gourd securely near the stem and using a drill/driver, bore holes where you made markings. Be sure to hollow out all the dots you drew for your pattern.
Pop In the Lights
Insert a string of small lights through the pumpkin’s bottom and push a bulb halfway through each hole. Run the lights’ cord from the bottom of the gourd to an outdoor receptacle.
