I've got all my fence sections done and painted and I'm thinking of making a pair of columns for either side of my sidewalk, nothing to fancy. I'm guessing they are just a frame of 1X2s covered with styrofome then painted. I have a couple of big blow mold pumpkins I wanted to put on top, the pumpkins are about 17 inch diameter and about 2 feet tall. Thanks. Also, how to you keep them from blowing over?? I thought about making the frame from PVC and then sliding it over rebar like the fence.
