Areas on the drawings that are filled with a dot pattern are gluing surfaces. White glue (e.g., Elmers) is
recommended, or a glue stick can also be used for larger areas. You may need to hold the pieces together for
a few minutes to allow the glue to set. This can be done by hand, small clamps, rubber bands or removable
(low tack) tape. Remember to use only a little bit of glue, as the more you use, the longer it takes to dry.
