Have an empty wine bottle and vinegar cruet in your show booth so people can see how nice a stopper looks in a bottle. Remember, there are people who don’t drink wine and might just pass by but if you show them other “bottle stopper” uses, you will get another sale. Many designs are more attractive in the bottle than either laying on the table or in a display stand with a dozen other stoppers.
For example; I make a door-knob shape stopper that isn’t exactly an attention getter in the display but when people try them in the bottle, they look nice and are very hand friendly. It’s a quick, simple design that you can add cabochons, coins, buttons, inlays, etc. on the top to create unique or individual designs.
