Here's an example of a very different collage as requested by a customer recently which I loved the results of. Its a three piece photo collage canvas total size of 48x48 inches (with the gaps). The customer requested a circular shaped frame which we don't do, so we designed a circular collage on a square canvas split over three pieces. this was the alternative. We even took into account the spaces to make sure that once it's hung its a perfect square with a perfect circle. Total of 170 photos used.
