But if carved pumpkin

You can carve some and artistic pumpkins freehand, but if you want to create really detailed carvings you'll need to use a stencil.

Stencils are easy to do and are available from most retailers. Then you are all set to add a candle inside the pumpkin to see the effect.

Or ask your Halloween party guests to bring a carved pumpkin to the party. Set up a special table to them all Potpourri on ( this will also enhance your party décor! )
