Making origami involves the use of various tools and materials that assist in the preparation of any particular structure. Glue is an important fragment in origami as parts of the paper are joined together with the help of an appropriate adhesive. Thus it is clear that for a majority of designs, without having the right glue, you cannot complete your origami model. The aforesaid statement is incorrect. The glue can be compensated with overlapping folds.
