Then one day I was looking at a pattern in the sofa fabric and thought, "That would make a great background."
Create a work of art using a patterned background you've photographed.
It's a good idea to go around snapping every pattern you see. You never know which ones you'll use. For example, when I took the photo of the floral fabric below, I had no idea it would be so perfect for the image of Primrose (inset).
