Koranna , the local fire marshals have a lot to say about indoor
booth layout, table covers, back and side drops, lighting, etc.
Having done indoor shows for a few years, I have found that what
works best for you may not be allowed. The promoter of your show
should tell you ahead of time what is allowed, and what is not.
There may also be promoter inflicted rules that will affect your
display. Just part of the dues you pay to play the game, although
the dues can be steep at times.
