I am currently working on a banner quilt, based on my old sunset photos. (It is not turning out as well as I had hoped but I may be able to rescue it.)
I just came across a blog post about using a sunset background.
Then I came across a news article about the wonderful sunset we had last night. The colours in these are amazing. You could think it was the end of the world in some, rather than the end of the day.
Seems my obsession won't be dying down soon.
