WHAT TO GATHER

Your starting kit.

  • Clean small cardboard box
  • Index cards
  • Ruler
  • Scissors
  • Paper tape

STEP 01

Prepare the starting piece

Measure the card width and height and choose a box with a little clearance. Check that its bottom and side seams remain sound.

STEP 02

Set out the shape

Trim the front wall only if it prevents easy access. Keep enough wall height to hold the cards upright without exposing rough edges.

STEP 03

Work the first section

Reinforce loose joins with suitable paper tape. Line the base with a flat clean card sheet if the original surface has uneven folds.

STEP 04

Build and adjust

Cut a few tabbed dividers slightly taller than the cards. Use plain practical labels such as projects, supplies, and references.

STEP 05

Finish and check

Add a modest number of cards and test removing one without bending it. Keep the box dry and avoid overfilling the dividers.

Before you begin.

What should I check before beginning?

Measure the card width and height and choose a box with a little clearance. Check that its bottom and side seams remain sound.

What is the main practical tip for this project?

An overfilled box makes cards curl; leave finger space rather than compressing the contents.
