We had some roof tiles (Acme brand, of course, suitable for dropping on the head of Wile E Coyote) left over from our recent building project. I thought I might try painting some with the kind of flower design that is the traditional decoration for narrow boats.
I drew out the design, traced it onto the tile, and filled in with gesso to provide a decent surface to paint on. Once painted I used a stencil to spray varnish on the painted area. It all worked OK, but I think the fact that I was copying meant I didn’t quite get the free, stylised look, and the colours are a bit light. Still, I quite like them!
