Simple wedding centerpieces in cube vases are very easy to make. Simply cut the button mums off the central stem and insert into vase.
You will need:
Cut the white buttons off main stem and insert a colored Pixie Pin in the middle of each. Pour rocks in bottom off vase, add water that has been treated with Crystal Clear flower Food (colored with Wilton Food Color if you wish to tint the water - Wilton stays true to the color while regular kitchen coloring does not). Insert the stems into the vase.
Mist well with either Finishing Touch or Crowning Glory.
