Sometime I have to exhibit photos. Now I have a project for a non-profit organisation, e.g. the budget is tiny - but the prints need to be large. Squaring the circle is never easy...

My prints will be color and b/w prints on RC paper, some of them will be very large, e.g. 2 meters by 1 meter (ca. 6 by 3 feet).

What could be a good method to mount and present these photos without spending a fortune? And did I mention that I am all thumbs?
