Ok Girls, here's my attempt ...
I added a thin border as the finished block was not quite 16 1/2" all the way round.
You will note my 'Feature' fabric really isn't ... in fact, it gets lost within the background ...
I had wanted a turquoise but it looked too different! Which I suppose was the point! D'OH!
Never mind, you live and learn!
I wonder if I'll get sent to the BOM HOF by Syrinx ???
