That's excellent Keith! And it's exactly the sort of thing my wife wanted me to make. But I ended up just making a blanket chest come window seat. It appears far more difficult to make furniture fitted - is it?
Very nice, and suitably unusual. Have you got photos of the process? I can't speak for the GW team, but If I'd made that, I'd have written it up along the way and hoped to be published. I'm sure many people would be interested to read how you did it.
