DIY Centerpieces: 1. Select two cylindrical vases (one a bit smaller than the other). 2. Place roses (or flowers of your choice) in the smaller vase filled with water. 3. Place hard candy sticks (you can find a wide assortment of colors of these hard candies) vertically in the space between the vases. 4. Fill it all the way up! 5. Tie a big pretty bow and you’re all done.
