I don't really have any interest in making a quilt this way (might be a good way to plan a watercolor quilt?), but I do appreciate the patchwork nature of mosaics (photo, ceramic, etc.) and had some fun playing with this site recently.
I tried it out with two photos from Christmas 2005 in France - I was thinking of that trip a lot as I worked on the mothers' day gift for my mom. The first photo is Chateau Villandry where we went on my 30th birthday (great gardens - many quilt inspiring photos stored away for someday); the second, a outside flower shop in the walled city of Dinan.
