Hi, I have displayed my instruments at a  few open air markets and those craft shows that are held in church halls and the like 

At a market I can put up my 3 x 3 meter tent thingy and display CBG's by hanging them around the walls and on tables. But I feel a bit guilty banging nails in a church hall wall to hang my guitars, so I came up with the display stand shown here.

What I like about it is that there is more of a visual impact than having guitars on individual guitar stands and laying on a table.

The main centre stand is a display stand for 6 instruments, but half of them face the wrong way when loaded up. This modification gives me the ability to show 12 guitars all facing the same way. Its portable, six screws and its all folded up, my individual stands are available for other instruments.

I have a 3 day craft show coming up to test it at, so let you know how it performed.

Cheers Taff
