Okay my knowledgable friends, On Easter Sunday this year I was all dressed up and on my way to church when I spotted this bird bath base. Of course, I had to pull over and throw it in the car. Now I want to use it as a side table outside and I have this perfect top. Please give me some suggestions on how to attatch the top. It is really heavy, but I am afraid it will tip if it is not attatched properly. Any suggestions will be greatly appreciated.
