Man, it was hard to get the walls into the grooves of the side supports! It's going to be messy when there is glue applied! I'm hoping that holding it all together for a little while, dry, maybe if the walls were warped, it will force them into being straight and so gluing them in will be easier than dry fitting them in. We'll see. But the sunny yellow looks okay with the white trim. I've painted the foundation gray in preparation for the brick.
