Fantastic paper model... However, I gave up on card stock models, beginning with this model. I buy 3mm-thick cardboard, from a framing shop, at Michael's. I print out the pieces of this castle, on full-sheet label paper, apply it to the cardboard, and cut it out to size. The 3mm-thick cardboard tends to bow, so I use Wood Glue, and I apply a balsa wood rectangular beam, from the craft store, to reinforce the long sections. It works, quite well, creating a durable 'paper' model, with strength, and heft. My cardstock models lasted about two games' worth; my 3mm-thick cardboard models have endured 3+ table games, with miniatures, without issue.
The Gatehouse comes in two versions: simple, and complex, with a working portcullis. I built the complex version. The wall sections have a 1.5-inch wide catwalk. The Towers are all square. The textures are superb, there is great looking shadows. Though the finished models are really nice looking -- with no painting required!
Furthermore, I am using the printouts from this set to cover round, oatmeal tubes, to create round Towers. This does require cutting and pasting, to match things up -- it requires some skill and technique, but most average adults can accomplish this without too much effort. I am applying the same techniques to rectangular oatmeal boxes, to make custom, though much larger, Gatehouse, for really large cities.
This set is worth every penny. Printing on full-sheet label paper, and applying to 3mm-thick cardboard, makes beautiful, durable models, which should last for years. As for appearances, they are very good. For mini's gamers, and role players who want to build a city wall, or a castle keep, this is the bomb! Cheers!
