I was just collecting ideas myself and haven’t actually built the wall yet. I’m thinking that the most difficult part will be planning it out so that the doors all look good together and that may or may not mean adding extra studs or supports to secure the doors to.

I kind of envision having thin molding covering the seams and maybe painting that molding a uniform color, as if to frame each door.

From your comment, it sounds like you want to join each door together. I was just going to secure it to the studs and get them as close as possible. But yes, if you want to join them, I guess biscuits or dowels are the way to go. I’m not skilled enough to make that look good though! 😉
