Assembling the Icosahedron

  • Prepare your faces -- 10  will have the base of the triangle at the bottom and 10 will have the base at the top.  The face above has the base at the TOP.

  • Fold on the solid lines so that the flaps face away from or towards the two faces you will be attaching.  Attach two faces together with either the flaps on the inside or outside of your icosahedron.  The two attached above have the flaps OUT. Glue from a glue stick  was used to make the attachments shown here. 

  • To make the top or the bottom, attach 5 faces together as shown above with the flaps IN, OUT, or any combination.  The top for the icosahedron should have the base of the triangles at the bottom of your faces and the bottom for the icosahedron should have the base of the triangle at the top.  The picture above is the bottom of an icosahedron.

  • When assembling the top, be sure to include a hanger -- sting , wire, ribbon.  You should secure the hanger in place on the inside of your icosahedron.  The top of an icosahedron, with all the flaps IN, is shown above.

  • Assemble 10 faces as shown above.  The position of the base of the triangles alternate TOP to BOTTOM as you connect them.  The one shown above has some flaps IN and some OUT.

  • Attach the two ends of the strip to make a circle as shown above.  This is the middle portion of the icosahedron.

  • Attach the top of the icosahedron to the middle portion as shown above.

  • Attach the bottom of the icosahedron to the middle portion.  The view above shows the bottom portion and middle portion (green) of the icosahedron.
