Trace the bottom of a 4 to 6-inch pillar candle onto the top of a pumpkin.
With a sharp knife, cut along the traced line. While cutting, hold the knife at an angle, this will create a cone shape. Discard the cut portion.
The candle should fit securely into the cut portion of the pumpkin. Adjust the size of the opening as needed. If the cut portion is too large to securely hold the candle, place a can inside of the pumpkin and place the candle on top of the can. This will create stability for the candle.
Arrange fresh flowers around the candle.
