I used a plain Kona Coal grey for the back but laid in a row of blocks for interest. I loved this fabric but it made me crazy at the same time. It is the London Underground map, however it isn't accurate!
The designers chose to make the map repeats flow together instead of have a clear definition so they have extended lines and moved stations. I am a little too purist for that so there was a lot of fussy cutting that happened to make it as close as possible to the authentic map.
The above photo makes me believe that my photography skills are improving too. Although even a blind pig finds an acorn sometimes.
Jack is now happily living on my Mum and Dad's spare bed, a thank you present for everything they do for John and me on a regular basis.
