A PRACTICAL HANDMADE PROJECT

Create a Cardboard Stencil for Geometric Shapes

A geometric stencil helps repeat simple outlines on paper. Large open shapes are easier to cut and trace accurately than tiny detailed openings.

WHAT TO GATHER

Your starting kit.

  • Clean thin card
  • Ruler
  • Pencil
  • Scissors

STEP 01

Prepare the starting piece

Draw a square, rectangle, or broad triangle inside a card border. Leave a generous margin so the stencil does not tear during tracing.

STEP 02

Set out the shape

Fold the card lightly within the waste area to start a scissor cut if needed. Choose an open-edge template if an internal cut is difficult.

STEP 03

Work the first section

Cut slowly along the outline and remove loose fragments. Check the opening against scrap paper before making a finished design.

STEP 04

Build and adjust

Hold the stencil flat and trace with a pencil kept close to its edge. Move your supporting fingers clear of the pencil path.

STEP 05

Finish and check

Lift the stencil rather than dragging it across the drawing. Store it flat and replace it when a worn edge changes the shape.

Before you begin.

What should I check before beginning?

Draw a square, rectangle, or broad triangle inside a card border. Leave a generous margin so the stencil does not tear during tracing.

What is the main practical tip for this project?

This is a drawing aid, not a cutting guide for a sharp blade.
