But -- now that the house is painted and the paint camouflaged the chips and sealed them, so they won't split any more, I think I'm going to leave it as is. I can repaint the strips to use them elsewhere. Of course that means I have to add corner trim at the bottom; when I replaced the broken trim, I left space for the foundation boards. No problem that a little time and paint won't cure.
I bought a 2' x 4' piece of quarter inch plywood to use as a base. It will extend a couple of inches beyond the base of the house and give some protection to the porches, which are just stuck on and vulnerable. I was thinking to put faux grass on it, but now I'm thinking to paint it with the same green as the roof. Cartoon grass for a cartoon house, eh? The house won't be attached to the base. It's big enough and heavy enough to be difficult to move as it stands alone. And the couple of inches will be enough room to display some quilts outside. :)
