Twenty sided ball made from greeting cards

 by hammer9876
It hasn't rained here in months, but every once in a while you just have to have a rainy-day project that recycles greeting cards. This finished ball is just over 5 inches (13.5 centimeters) in diameter.

Step 1: Gather materials

You will need:
1) 20 greeting cards
2) scissors
3) 31 paper clips
4) jar lid (mine was just under three inches (3" or nearly 7.5 cm)
5) ruler or straight edge
6) pen or pencil
7) glue
8) string - twelve inches or 31 centimeters is plenty
9) one sheet of notebook paper
10) compass (Don't panic. It is used only to score the cards for folding.)

I have a gamer brother who would love this as a gift.  I just need to draw numbers on the sides... ^^

That would be easy enough. I would do it before cutting and folding and gluing. Good luck!

The proper term for a twenty-sided figure is a "Dodecahedron" Just to shorten up the title ;) Great idea otherwise! this would make excellent Christmas ornaments! 4/5

Dodecahedron is a 12 sided polyhedron. The proper term is icosahedron. See http://www.georgehart.com/virtual-polyhedra/naming.html where it states. "Similarly, icosi-, meaning 20, is used in the 20-sided icosahedron."

Ahah! Pardon me for my misconception prior to your previous comment. :D

It's a great idea! But just to prolong the reply list: Sorry no dodekahedron :-] The correct name would be "ikosahedron" because greek "dodeka" means twelve and if you count the triangles of top bottom and middle row, there should be twenty - greek "eikosa" -triangles! And by the way, if one reads until the end there is even written in the last sentence which platonic solid is made by this work ;-)
