Today I installed the tower and all the gingerbread trim.
I added a cork scrapbook paper “floor” to the tower room to give it an outdoor feel since I plan to turn it into a rooftop garden with a small “shed.” The tower walls aren’t as straight as I’d hoped, but it’s not noticeable unless you look at the roof from above.
Keep your brackets and gingerbread as straight as possible. You may want to measure the side walls to space the brackets evenly, though I eyeballed it and it turned out fine.
