I was looking at a very striking store display the other day. It was an outdoor scene all in snowy white.
You know all they did? They got rocks and washed them. Cut some sturdy branches from bushes that had lost their leaves. Cut some evergreen boughs that were tree shaped and bought some of those small paper mache deer. Set it up in a silver wrapped box and sprayed it all with spray on snow. Of course, they then hung some ornaments for sale on it....but it would also make a great centerpiece or entertainment center topper or room decoration even without the extra ornamentation. Super inexpensive, easy to do and fast to put together and finish!
