WHAT TO GATHER

Your starting kit.

  • Clean, dry cardboard with uncrushed edges
  • A ruler, pencil, and scissors suitable for the board
  • Paper glue or paper tape as required by the joins
  • Scrap cardboard and a protective work mat
  • Bookbinding awl, binding needle and thread, and a suitable protective backing

STEP 01

Measure and prepare

Cut two matching triangular end supports with a broad V notch at the top.

STEP 02

Lay out the construction

Join them with two sloping cardboard panels to form a shallow cradle with an open valley.

STEP 03

Join and shape

Rest a folded scrap booklet in the valley to check alignment before using a bookbinding awl over an appropriate protective backing.

STEP 04

Check the result

Keep fingers away from the awl path and use the tool according to its instructions; cardboard does not stop a sharp point. Let all adhesive dry before fitting the intended lightweight contents. Place the project on a flat surface and check that its joints sit square. If a slot tears or a wall leans, remake that piece from sound cardboard rather than hiding the weak join with decoration.

STEP 05

Finish and keep

Smooth exposed rough edges with a thin paper covering where needed, without blocking working slots. Keep the project away from water and heat. Recheck the joints after a few uses and replace a worn piece if it bends or loses its shape.

Before you begin.

How wide should I cut the slots?

Measure the cardboard thickness and test a slot on an offcut. The pieces should slide together with light pressure; forcing them can crush the corrugation and weaken the join.

What should I check before beginning?

Keep fingers away from the awl path and use the tool according to its instructions; cardboard does not stop a sharp point.
