Build a Cardboard Envelope Drying Rack

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

STEP 01

Measure and prepare

Measure six slots 15 mm apart along two identical 160 by 50 mm cardboard strips.

STEP 02

Lay out the construction

Cut each slot halfway down the strip and slightly wider than the thickness of a third crosspiece.

STEP 03

Join and shape

Slot the two strips over a flat rectangular base with matching notches, keeping the envelope supports upright and parallel.

STEP 04

Check the result

Use this rack for light dry paper work; wet glue should not touch the cardboard base. 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?

Use this rack for light dry paper work; wet glue should not touch the cardboard base.
