You need: 20 equilateral triangles cut out of paper or card stock and some tape.

First tape one edge of each of three triangles to the edges of another triangle to create a large triangle from three of the original pieces. Repeat.

Next, tape a pair of triangles together, edge to edge. Repeat five more times.

You should have 2 large triangles and 6 pairs of triangles.

* * * * *

Now, tape one pair of triangles edge-to-edge with the corresponding edge of each of the three single triangles you added in step one. See diagram for an example.

* * * * *

Tape the edges of those triangle points to the closest edge. Do this six times, three times on each configuration. You'll end up with two domes that have staggered edges.

* * * * *

Finally, tape the dome-like sides together so that the points fall into the dips along the edges.Tada! You've done it! Try it with paper mache, fabric, or whatever you'd like! I plan to make an enormous throw pillow for one of my daughters who is a participant in two different D&D gaming groups. Also, she likes squishy things.

Awesome

ReplyDeletewait im confused... why r there 2 figures? are they both still 20 sided?
