WHAT TO GATHER

Your starting kit.

  • Clean cardboard box
  • Paper pattern envelopes
  • Ruler
  • Pencil
  • Scissors

STEP 01

Prepare the starting piece

Measure the envelopes and select a box with a little room above and beside them. Remove staples or loose tape from reused packaging.

STEP 02

Set out the shape

Mark a lower front wall while keeping the back and side walls tall enough to support the envelopes. Cut and smooth the exposed edges.

STEP 03

Work the first section

Reinforce any weak seam with suitable paper tape. Add a flat bottom liner if the box flaps catch the envelope corners.

STEP 04

Build and adjust

Cut a few broad tabbed dividers and label them by project type. Keep pattern sizes and source references with their original envelopes.

STEP 05

Finish and check

Load the envelopes loosely and keep the file dry. Do not compress folded tissue patterns or store them against damp exterior surfaces.

Before you begin.

What should I check before beginning?

Measure the envelopes and select a box with a little room above and beside them. Remove staples or loose tape from reused packaging.

What is the main practical tip for this project?

Store the file on a stable shelf; a cardboard divider is not designed to support heavy binders.
