I'm putting on a plant swap for my neighborhood association next week.
I've never even been to a plant swap, but thought it sounded like a
fun idea. I'm looking for input on how it should be run. Are their
standards or guidelines, like swapping plants of the same size? Do
folks set out their plants like a garage sale, on a blanket or table?
Like I said, I've never been to one and I'm not sure what to expect or
how to set up the area. I'd love to hear even the most basic of
suggestions.

Thanks.
