For the exhibition I am wanting the show to be as accessible as possible, so Braille is being printed as a introduction and description of the show.
As I was researching I found that clear plastic stickers can be printed also and thought about adding small poems within the tent space.
These would be a nice addition to the tent, perhaps on a few extra clouds or leaves?
A few sites that provide Braille printing services:

http://www.pia.co.uk/en/services/braille.aspx
I used http://www.access2print.co.uk as they were quite reasonably priced compared to others.
PIA have some interesting resources on their site also.
I was interested in the alternative Moon method to Braille: http://www.pia.co.uk/en/Resources/WhatisMoon.aspx
