My wife Ethel came up with this idea, which I think is super. She took some old golf club sleeves cut them to size, put them in the center of the pots & filled with cement around them. Then placed artificial flowers in them. When they get weathered, simply replace. In this case the pansies are new, the rest I air brushed them to revitalize the colors, came out fine. You can use any P.V.C. pipe for the centers. We had some pretty strong winds & they did not move. HAPPY FLOWER POT MAKING.
