How to Minimize Seams in Paper Models
Scoring bases such as chipboard is an effective way to create partial models that stand on their own. However, the drawback is that a folded base creates a larger seam or gap where the two sides come together. The existence of seams or gaps along the sides is a general problem with most scratch built models. Getting the paper to come together at the seams is actually one of the largest challenges you’ll face when building these structures.
Luckily there is a relatively simple fix. Instead of trying to get two pieces of paper to come together perfectly where the two sides come together, simply fold the paper over the seam. When cutting the paper, leave about ten to twenty percent extra for the fold over the scene. Use the same folding tools and techniques to get a quality fold over the joining of the two sides.
Once the first piece of paper is folded and adhered over the seam, overlap another piece of paper to cover the rest of the side. The seam where the two pieces of paper come together will be much less visible the seam where the two sides come together. You can even seal the seam with a coating of diluted white glue to further camouflage it.This strategy works best if you fold the paper over the front and back of the building and leave the seams on the sides. (In most cases the sides of your building will be less visible on the layout since they’re likely to facing or up against another building.)
