Hinged panels are free panels that are not being forced straight by being glued to other dollhouse parts. If they warp, you will notice it. It will prevent the door from closing correctly and you will be left with gaps around the panel sides. The wood of a tab and slot dollhouse is very thin and so it is more susceptible to warping but it is much easier to fix than a thicker MDF panel would be.
The best way to prevent warping is to finish the panel in its entirety before hinging it to the dollhouse. If your panel looks straight, once you paint or wallpaper it, it will warp. You have to make sure that your paint and wallpaper is dry before you begin hinging. Always allow for everything to dry with weights on top of it and finish both sides of the panel at the same time.
My front panels were already warped even before I began working on them. For now, that's fine. I glued the interior surround trim to the panels and clamped them down to dry. The surrounds straightened them a little but not enough. These panels have to be table top flat for them to look right. This is not going to be a frilly dollhouse like the Gloucester was, where I could hide any gap caused by warping with fabric. This dollhouse is just going to be stucco and much plainer so I have to make sure there are no gaps.
I will return to this issue later when I get ready to finish them.
