I have no idea how you got that great dimensions diagram off that MR photo I posted up, but if you could do it again you would totally be my hero!
Outline with rocker, and you TOTALLY have to share how you did that, as I would use the hell out of that technique if I had the knowledge/means to do so!
And this one if it is easy and you can pull it off, but mainly the one above.
Again neira, you are so my hero!
