Need new saddle bags

The zippers on the saddle bags for my ATV have been pretty much destroyed by the elements. They won't unzip or zip fully closed. I need to get some good canvas and make a new set, this time custom made to fit my little Honda rather than a pre-made store set of tank bags that were meant for a machine twice the size of my little Honda ATV.

I'm thinking I will stop in at the fabric store and get some cotton canvas that I can put through the embroidery machine and do some custom designs on, then sew them together into a set of specialized tank bags that include pockets that my Mag Light will actually fit into and a place for my camera and other essentials along the trails.
