What, no paisley lovers. Or a nice tweed.
Patterns, whether paisley or Mossy Oak camo are the absolute worst backgrounds to use as a display. Small objects will disappear.
If you just have to go with polka dots, Army digital camo or paisley.......get some place mats at WalMart and lay that on top of the table cloth. Place product on top of that.
Whatever color or type of cloth you choose......does it convey the idea that your products are worth what you are asking?
Several years ago I had a table next to a custom knife maker at Dallas Market Hall. His knives looked pretty, buffed to a high sheen, razor sharp, beautiful grips, nice craftsmanship.
He was asking upwards of $300 for a 2.5"- 3"fixed blade, his 4"-6" blades over $600. Around twenty knives total lined up and not a price tag in sight. He didn't sell a one. He didn't use any table covering, just laying his knives on the bare table top.....a very used, beat to heck, dirty table top that is the reason you cover tables. He looked like he just came in from baling hay in the back 40.
Perception is reality. The quick glance that people would give his table never caused many to look over, much less linger over his knives. At a gun show you have seconds to give a positive impression. I'm not saying a vendor needs to wear a business suit or hire booth bunnies......but think about what a successful salesman would look like. The first impression my buddy had was "must not be very good knives" based solely on his appearance and his table. Indifference to how you display your product reflects negatively on the perception of your product.
No price tags? It wasn't because he forgot them, I offered him some if he needed them....."no, I want people to ask". Thats nuts. So, some random guy, with random unmarked homemade knives of unknown materials and not even a sign or business cards or a sign saying "POR" (Price On Request). Which really means Price Overly Ridiculous and buyers pass on by. Could you come up with a better recipe for not selling anything?
