I wish we had something like Square here in Aus, because I'm sure it would help with my sales at fairs too.
I know what you mean about getting better at showcasing a professional look, Jere. I feel like I'm always tweaking my display each time, trying to find a way to make it look as professional and inviting as possible.
I'm expanding to two tables at my next market, I just have too much stock to be able to display it clearly on one. Luckily the cost of table hire at these markets is low, so it's not a big gamble.
Jacque, let us know how your big show goes! How do you display your stuff? Do you have testers of your perfume oils and such for people to smell and experience?
