Tube vases are popular these days because they correspond to the minimalist style which is on top today. But you can not spend tons of money on a tube vase by a famous designer but create one yourself. The supplies are test tubes and a holder, spray paint, pencils, foam board. Cut holes in your foam board so that the pencils can stand upright. Place the test tubes over the pencils. Spray the test tubes with paint you like. Let dry for 1 minute in between coats, add water and flowers and enjoy! Your cool and fashionable vase is ready!
