Brush a thin layer of decoupage medium onto your candle.
Unfold and separate your napkin so that it's just one-ply. Wrap it around the candle, smoothing it out. Brush on another layer of Mod Podge over the napkin. Let dry.
Add an additional coat of Mod Podge around the candle.
Wrap the napkin around the bottom of the candle and Mod Podge down. Let dry.
Trim off the excess off the top using scissors.
Light up your decoupage candle and enjoy!

Notes
Tip: use a piece of plastic wrap to smooth the napkin out. Place around the candle and use your fingers to smooth (gently so as not to tear the napkin).
