Score and cut out parts. Make sharp folds, as above. (Except for the hinge fold on the back of the lid. Try
to make this fold wide and deep, but without breaking the surface of the paper.)
Make the liner first, with all tabs folded to the outside. Glue liner
to the top of the body, with the whole thing upside down, on a flat surface.
As an option, you can install a 1/8" strip of "fridgy magnet" to the inside
front of the body and lid, to act as a catch. Then, fold and glue the
body, around the liner.
Install the lid by gluing the hinge to the back of the body.
