A bud vase filled with water, a wide flower (real or silk), and a small tealight. This looks like spring or country-simple, but you can do whatever flower you want (and tealight) as long as it creates a wide enough base for the candle.
I want to do this for the center piece of my table to add some color. “Citrus Surprise” Cool icy and refreshing. A gelatin like material suspends fresh citrus fruits in tall glass cylinders. Spheres of spider mums top these citrus coolers.
