If you go canvas and Gallery wrap, you have to consider the image that will be wrapped, easiest way to handle this is a solid color, the stretch can get a bit tricky as you have lineup the edges and hope you didn't skew too much (if you use Epson large format). You can also mount the canvas tiles to gator and then just frame them with a simple metal frame. The frame will cut just slightly into the image, 1/4" each side, but it will look fine. You can mirror the edges, but IMO this tends to look worse than a solid edge often times the edges look like kaleidoscope images. Distracting to me.
You can also go the way the the big shops, Midwest Photo for example do, they will mount the prints on a surface then place a solid edge around the piece, basically a box. Most times this is black or dark grey and you can easily hang these since you have the inside edges. For mounting, you would want to consider eye screws as they will fit inside the box and help hold the pieces flush to the wall.
