Origami Juggling Ball

Here's how to make a nice, sturdy juggling ball (or hacky sack) out of cereal box cardboard.

This design is based off of Jennifer F's video "Greek Paper Football".

I used regular cereal box cardboard, which is something like .25mm thick...

Step 1: Make the Strips

Materials:
Scissors
Cereal Box Cardboard (or any thin cardboard, I suppose. You could probably also use thick paper, or thin plastic)
Ruler
Paper Cutter (optional)

Cut six (6) 20cm x 1.1cm strips
which is about 7 7/8 x 3/8 in

Step 2: Bottom Half

Weave five of the strips together, to form an interlocking star. Once you've done that, check out this video for adding the sixth strip.

Step 3: Top Half

Ok, this part is the most difficult: You need to weave in the final strips, with increasingly less space to work with.

A few tips:
When in doubt, make sure the strip alternates over and under
Keep the pentagons tight, and make sure the sides of each all go in the same direction.

The video's probably more help than the pictures :D

Step 4: Finishing Touches

To complete the ball, slide all the strips around until the joints are covered by other strips (see video) this makes the ball more sturdy.

Now you can make some more to juggle with, or play hacky sack with, or just throw at the people nearest you.
