I remember standing at a bus stop in the middle of winter some years ago in the downtown area. There are many old buildings down there and many have nice decorative designs in them. I saw a really nice design at the top of the Royal Bank of Canada Bank and went home and drafted the design. I later actually put it in a Round Robin quilt I was working on with a Canadian group. It turned out really nice!
I too am forever getting inspiration from the wildest of places. I have seen designs in tiles too...
