1.) Display in surroundings – Let's say you are a potter, and you are trying to sell your flower pots for the upcoming spring flood of gardening gifts. Why not take a half dozen planters (or more) and plant a beautiful array of flowers and plants in them? When people can visualize how the planter is going to look in their yard, they are usually more inclined to make a purchase. Help people 'see' your craft in their homes, and you increase the chance of a sale.
3.) Create a theme – If you have outdoor crafts that people can use, then why not turn your craft show booth into an outdoor wonderland? You can have patio furniture, a fountain, and maybe even some 'grass' in the booth. If you create a theme, and then display your products within the confines of the theme, you are not only going to attract more people, but you will make more sales, too.
4.) Use the customer's senses – The more you can appeal to all of the senses (touch, smell, see, hear), the more you are going to sell. If you have knitted sweaters, let them hold, smell, and see the goods. Let them try it on; give the customer a sensory experience, and they will be more inclined to make a purchase. You can do this with a variety of crafts that appeal to all of the senses.
