PAPER

The weight of paper products is determined by how much a particular quantity weighs...which is why the rating is called its "weight". "Sheet" paper products - like what we use in our printers, and hence for these castles - are rated by the weight of a ream. There are 500 sheets in a ream, so if the weight rating of your paper is "22", then 500 sheets of your paper weighs 22-lbs. (standard printer paper). At 30lbs-40lbs we call it construction paper, and anything above 50-lbs is usually considered card, or card stock.

Standard paper is suitable for most paper models, including our castle designs. However, the larger the pieces, the less stable they will be. That is why most paper buildings are actually constructed of heavier paper, also called card.

For castles (and other buildings) card is is the preferred weight to use. If you cannot find card stock sheets, it is perfectly fine to print your castles on regular paper, and then glue this to heavier material like cereal box or other light weight packaging. Unless you are building large enough to actually fit into yourself, you should stay away from corrugated cardboard.
