I need ideas to display my bubble magnet for a craft fair this weekend

Put them on a cookie sheet and prop it up from behind (or use a plate stand to set it on). That is the first thing that comes to mind.

I sell mine two different ways. The first, and probably the bes if you are selling them individually, would be to put them on a dry-erase board. Magnets stick to a dry earase board (at least the ones I have), they are easy to prop up on a table. The way I sell my sets is to package them in sets of 4 or 6 in small ziplock bags. I fold the bag up and then staple them to the bottom of one of my business cards. Dry Erase boards a re fairly inexpensive and come in handy around the house when you aren't using it for a craft show. Hope you have an awesome show & hope these ideas help out!

i am selling these types of magnets and what i have done is gone to home depot to get a sheet of metal (that they use for roofing and the like) and cut it up into pieces for my magnets...i tried tinfoil, but it doesnt work.
