This is part quilt and part painting. I tried to find a style which is remotely reminiscent of an ancient Italian fresco. I made the quilt block and then put paint upon it so that it looks a bit like a part of a wall. The quilt was then fixed on a painted canvas.
Here is an example of an Italian fresco, it was photographed in Siena. I found this lovely picture on this site: http://www.dgolds.com/photos/Italy2002/images/Siena/007FrescoInCourtyard.jpg
