I've seen these around cyberspace and loved the concept. I figured that 6" X 8" would work well - room for your mug plus a little extra for that little extra to snack on. I had something that I thought might work. A quilt top half finished. Half finished by someone else. Yes, folks, the queen of unfinished projects and UFOs BOUGHT someone else's UFO. What can I say - I thought it was a good idea at the time. The centre piece was stuck down - a mosaic - and the rest of the background had bits drawn on in chalk. Like this.
