My sister and I are very fortunate that we choose a booth in a center isle, instead of a booth you enter into. Because our shelves cut down the center of our booth we have two separate areas to stage with product..
It's also good to specialize, then your customers know what to expect, and it makes it easier to decide what to buy when thrifting.
It feels great to have a customer say, "I just love all the cool stuff you have!"...................Jolene
