Sometimes it is tempting to think you need to make a huge spread for a home jewelry show.
I have found the more simple you keep it the better. Some cookies, fruit...maybe some cheese and crackers. That's enough. Nothing that needs to be cut, served or that is too messy. Just a snack...a little treat.
To avoid accidents, it is also a good idea to keep refreshments and food away from your displays...preferably in another room.
People are there to see your work and I have found too much food can be distracting and most of the time is a waste.
Also, be sure not to have chocolate or anything too greasy...or you will be cleaning your jewelry all night!
