I recently visited a couple of out-of-town antique malls. It was interesting. One thing stood out - the clutter effect. Many of the booths that seemed the most cluttered were having sales - 20% or 30% off everything in the booth. The regular prices were low. It was obvious they were just concerned about low sales.
I'm sure there were treasures to be had, but it just looked like a mass of unwanted junk. I found myself standing in the aisle and doing a quick booth skim. I didn't even want to enter those booths. It looked like exactly what I want to steer clear of. I suspect many customers felt the same way and the poor vendors are no doubt thinking that if they just mark things down, those knick knacks will sell.
It also brought to mind something else that I have noticed more and more. About 5 years ago, having vintage smalls were all the rage -especially old kitchen items. Many people decorated with all sorts of things from especially the 40's and 50's. Magazine photos were full of photos examples of people who achieved the perfect vintage look.
Now, in those same magazines, you still see some vintage items but having too much now looks overdone and sad. There will likely always be a draw for vintage items, but the way they are used and showcased changes. A vendor needs to stay on top of the shifts in styles!
As I've said before, the next hot style doesn't seem to be here yet, but people know what they are tired of! Unless you are a specialty booth with continuing good sales, you need to make sure your booth isn't selling mostly what most people no longer want to see. Look through current magazines and popular Pinterest pins to see what is trending in terms of styles and colors. Keep your booth current and you won't have to have a booth wide clearance sale!
