Like another project of mine, "Heart of glass" (here), this constitutes an unconventional Valentine's gift, or simply a nice project if you like folding paper.

Technically speaking, it's the first stellation of an icosidodecahedron (info here), but I like to think it's a "paper heart" :)


A 25cm tall (almost 1 foot) paper stellated icosidodecahedron.

Bill of materials

You'll need:

  1. 30 rectangular sheets of paper. I have used standard A4 paper, 80gr/sqm, red. A rim of 100 sheets was 3€, around 3.5$.
  2. about 3-6 hours to cut and fold, about 1 hour for assembling. The cost of this item depends on your salary :)
  3. 1 metric ton of PATIENCE! :) And this is PRICELESS :)

No scissors, no glue, no ruler, no pencil. Just paper, time, and patience.


First, you need to prepare 30 sheets of ratio 1:sqrt(3). Then you need to cut and fold 60 modules out of them. Then you need to assemble the heart.

Let's see these three things step by step.

Step 1: Making a 1:sqrt(3) Sized Sheet of Paper

  1. Start from a rectangular sheet.
  2. Fold along the long size.
  3. Unfold
  4. Bring the upper left corner along the fold, such that the upper right corner is divided in two angles
  5. Flip the sheet
  6. Fold the paper and make it slide until you reach the point where the upper right corner meets the fold as in point 4 above.
  7. Fold the paper there and mark the fold with your nail.
  8. Gently cut the paper following that fold.
  9. You're now left with a 1:sqrt(3) sized sheet of paper, with a fold marking two equal sides.
  10. Separate the two sides.
