First time mosaic! Necessity, they say, is the mother of invention. We needed to block off a window in the front porch but, with the best will in the world, we were never going to match either the render or the colour of the outside wall. So I had to think of a way to do it and this was the result! A rather large house number plaque! Still, if we get a short sighted postman it may come in handy!
