now this is only my opinion, but to me product presentation is 99% of what makes me stop at a booth. i rarely give the person at the booth a glance. until the product has "taken" me-then i focus on the rep and ask questions.
if i may suggest this, make your display absoloutely STUNNING! keep it simple yet elegant. what i would think of if i was a diva, (and good marketing strategy) dont let the table covering compete with the merchandise. maybe a turquoise blue velour table drape. maybe tall plastic cake stands spray painted gold (cake decorator supply) and edged with a "crystal" beaded trim (fabric store) and white lace paper doilies to set your products on.
space them apart enough that they dont distract from eachother. make them different heights. the lower ones in front and then a middle height and tall in the back. you can use strurdy cardboard boxes or bang some wooden ones together-then cover with your velour drape.
presentation means alot. it reflects you and your product. if you make it look really really special, like you really put some thought and effort into it, there will be a perceive value to the product itself.
anyway, wishing you good luck!
