I purchased the vase with the cooper arrangement. The arrangement came with more pieces than shown in the picture. It is very full and beautiful. I suppose you can use as little or as much as you like! I put bubble wrap on top of the sand in the vase to add height to the arrangement.
I bought the copper version for our new office and although this arrangement is quite high, we placed it on the front desk and it's a showstopper! Our walls are a deep, rich green and the light color of this beautiful bamboo vase and the copper stems really pops! Assembly was no problem at all. I did add some rocks for weight but received many more twigs than I expected, so the arrangement is nice and full. If I had room for it, I'd go back and buy the green version.
