Rita & Kim!
How exciting that the FB group is emerging from hiatus! Kim, we'll try to plan around that date if we can, so people can attend both swaps if they'd like. Hopefully you'll be able to check out our swap as well.
How does the FB swap work? I know some swaps give "tickets" for what you bring, which you then spend on what you want. We're more of a plant sharing party without that kind of organization.
We do try to organize a lot of the swapped plants ahead of time, using the seed swap tool here. It's just easier to drop off a pre-organized group of plants for person A, person B, etc and then enjoy the camraderie of the swap. Before we started doing this, I think I spent most of my time "pimping" the plants I brought!
