Find a design that you like and photocopy it to sheets of velum paper.
Using a papercutter, cut the sheets to fit the size of the cylinders (you may want to use cylinders in a few different sizes and group them for visual interest).
Wrap the velum around and secure with invisible tape.
Fill 3/4 full with water, add in floating candle and voila! Chic decor on a dime!
