A pop-up retail space is a venue that is temporary: the space could be a sample sale one day and host a private cocktail party the next evening. The trend involves "popping up" one day, then disappearing anywhere from one day to several weeks later. Wikipedia
I participated in the shop last Saturday. It was a beautiful fall day. There were lots of great vendors there. Here are a few that I met.
EVLK Designs was their with a great collection bags and other accessories.
Have a fun day!
