Garden Arbor

Very nice!

Are the bottoms replaceable or just decorative plinths?
The bottom trim are nailed and glued, but could be replaced without much effort. They are decorative, but also gave me a surface a board's width away from the long legs in order to drive stakes into the ground next to them. I screwed the stakes into the bottoms to hold the arbor securely. My sister has 6 grand kids who play in her yard often. The arch is very heavy and I was worried about it toppling down on top of one of them.
