For larger models you will need larger or thinner paper, possibly from online shops. Boxpleated models require thin paper, such as sketching paper.

Lines on a crease pattern may be indicated by \u2018mountain\u2019 or \u2018valley\u2019 folds to show how the folds alternate. If you\u2019re particularly skilled at origami, they become useful instructions for building models.
