Weaving Polyhedron offers a series of weaving materials and finished products for individuals interested in geometric shapes, creating beautiful paper crafts with innovative weaving techniques. This product features materials for constructing small triambic icosahedron, which is considered an advanced weaving project but is also the most beginner-friendly in our store. Each package includes 6 sets of materials, allowing you to create 6 small triambic icosahedron. The materials are pre-cut and scored for your convenience. In geometry, the small triambic icosahedron is considered a stellation of the icosahedron. Imagine extending each face of the regular icosahedron outward, and the resulting first layer of intersecting faces forms the small triambic icosahedron. However, in the weaving technique, it is envisioned as a polyhedron formed by extending each face of the regular icosahedron outward to create an appropriately tall triangular pyramid, where the lateral faces of this pyramid are isosceles triangles with a vertex angle of arccos(-1/4). From a weaving perspective, its weaving structure is similar to a rattan ball. In other words, all polyhedra formed by replacing each face of the icosahedron with a triangular pyramid have a rattan ball weaving structure, but the angles at which the weaving strips bend differ. For example, the great dodecahedron, great stellated dodecahedron, and so on.
