Oh, sorry, didn't mean to confuse.  Those parts are dynamic, I just meant make the whole thing that way, but then I think I'd lose the conforming fit of the top and I like that.  I may just go with the first result and postwork the fold out.    It would not be hard to do.  

Trying a couple of other ideas, but like you I have other projects buzzing around in my head, so the cloth room may be a gradual learning experience for me.  Thank you for the help.  :)
