Open-Wing Butterfly Mosaic

Before you build with real tiles

• Lay all six squares and 16 equilateral triangles flat, with tips pointing outward. No right triangles, supports or upright antennae are needed.
• Use the top view to compare the silhouette. Keep the larger upper wings, smaller lower wings and inward notches; do not fill the design into a rectangle.
• This is Dadafu’s flat adaptation, not the folded 3D butterfly in the official tutorial.

How to build it, step by step

1. 1. Make a narrow body

   Add in this step: 4 square tiles

   Join four orange squares into one straight column. The top square is the head.

   Hands-on tip: Keep all four squares flat with full edges touching.

   

2. 2. Open two broad hexagonal upper wings

   Add in this step: 12 equilateral triangle tiles

   Use six pink triangles for each hexagonal wing. Join an inner upright edge to the body and let the broad outer edges spread outward.

   Hands-on tip: Bring all six triangle tips together at each wing center. Match full edges and keep every tile flat.

   

3. 3. Add smaller lower wings and keep a waist

   Add in this step: 2 square tiles

   Join one purple square to each side of the lowest body tile. Leave the spaces above them open to separate the wing pairs.

   Hands-on tip: Do not fill the gaps. Each lower wing joins only the lowest body square.

   

4. 4. Finish the small lower wing points

   Add in this step: 4 equilateral triangle tiles

   Add one triangle to the outside and one beneath each purple lower wing. Both wing pairs are complete.

   Hands-on tip: Point lower tips toward the tail and side tips outward. Never overlap tile faces.
