MDL0020 - ORIGAMI - INSIDE-OUT SQUARE BOX

Text-Only Instructions

Credits and Resources:

This model was folded by me without any external reference or resource.

If you are aware of any other source where this model or similar might be listed, please let me know so I can reference it under this heading.

Paper to be used: Square, any size; use large paper to practice with at first.

Folding level: Intermediate

Steps: 18

Description:  This is a fairly sturdy, flat square box or tray. A lid can be made by altering Steps 3 and 5 (see "Remarks" below).

The sides of the box will be two-layered. Depending on how the triangular points are folded in the last steps, they will either form a small feature on 2 sides of the box or there will be a vertical slit if they are folded in under the sides of the model.

Remarks:

Remember, even if you have memorized the folding steps for fairly simple boxes, it might not be easy to fold a perfect box shape at first.

Keep at it. It takes precise creases and a fairly light touch to produce great-looking boxes. Practice makes perfect.

A lid can be made for this box by altering Steps 3 and 5.

Instead of folding the edges in to meet exactly on the center vertical and horizontal crease lines, leave a slight gap when you fold your edges inwards in Steps 3 and 5.

This will result in a lid, identical to, but just slightly larger than your box.

Making a lid that fits perfectly may take some practice and a little guesswork, so experiment with copy or other scrap paper first.

If using two-sided origami paper, lay your paper with the patterned or colored side down before starting to fold. The color or pattern will be visible on the outside of your box and/or lid.

Step 1

Place a square piece of paper down on a hard, flat surface with its edges to the left and right, top and bottom.

Step 2

Fold the top edge down to meet the bottom edge to form a horizontal center crease line.

Crease and unfold.

Step 3

Now fold the top and bottom edges to meet at the center. Crease and leave folded.

You should have a rectangular piece of paper with the top and bottom flaps meeting at the horizontal crease line.

Flip the paper over.

Step 4

Fold the left edge over to meet the right edge to form a vertical center crease line.

Crease and unfold.

Step 5

Now fold the left and right edges to meet in the center. Crease and leave folded.

You should end up with a square made up of 4 small square-shaped flaps which come together at the center of the model.  Make sure that these flaps lie straight and do not overlap each other.

Step 6

Working with the 2 top squares only, prepare to make 2 squash folds by folding the top layer of each square diagonally upwards and outwards to meet the top left and right corners of the square. Then unfold both folds.

Step 7

While holding down the bottom left flap with your forefinger, lift the left top flap up a little and carefully pull it outwards to the left with the forefinger and thumb of your other hand.

The bottom of the model should stay as is while the top left flap will first tent up and then fold outward to form a triangle extending out to the left of the model.

Press flat and repeat the squash fold with the top right square as well.

The top part of the model will now consist of 2 triangles that seem to be pointing away from you.

Step 8

Turn the model around 180 degrees so the triangles formed in the previous step are now pointing towards you.

Step9

Repeat Steps 6 and 7 with the left and right squares that now form the top part of the model.

You will be left with a shape resembling two diamonds positioned adjacent to one another, lying on top of a square.

Step 10

Focus on the center of your model where the corners of the two diamond shapes meet.

Fold these corners outwards to the left and right, respectively. Press flat.

Your model will now have a smooth surface comprising a square at its center with two triangles, four layers thick, pointing to the left and right.

Turn the model over.

Step 11

Focusing on the square center of your model only, fold both edges that are lying on the horizontal crease line upwards and downwards, so they meet the top and bottom edges of the model.

To do this, start with both forefingers together at the center top or bottom and move outwards, but stop where the square ends.

There will now be a thin band lying flat along the top and bottom of the square and four pockets or corners standing up at the left and right ends of your model.

Step 12

Start to form the left corner by following the thin band nearest you to the left until you are stopped by the corner flap that is standing up in the air.

Step 13

While gently pulling the thin band toward you, pull the point that is standing up in the air to the left and down while opening the corner from the inside.

You might find that the whole left corner seems to become undone with the side of the box flapping out to the left, but don't worry. Once the corner has been turned inside out, simply press the side of the box back into shape so it forms a 90 degree corner and reinforce with a strong crease.

You will notice that there is still a triangular flap that should remain flat on the folding surface at this point.

Step 14

Repeat this step with the right flap to complete this side of the box.

Step 15

Turn your model around 180 degrees and repeat the previous step to form the last side of the model.

Step 16

Fold the triangular flap that is still laying flat on your folding surface up and over the side of your box, tucking its point down and pressing it flat against the inside edge of the model.

Step 17

Repeat on the opposite edge of the box.

If preferred, for the sake of extra durability, use a dab of glue to secure the two points you have just folded over on the inside of the box.

Step 18

Alternatively, fold these triangular flaps in half so their points touch the vertical slits on the side of the model.

Then fold them upright, tucking them in underneath the folded-over sides.

They will disappear, locking the sides of the box into place. Glue might not be needed if this alternative is used.
