A cute container made from either a .5 mL or 1mL plastic Coke bottle. As a bonus, it makes a very satisfying snap when opened and closed.
I cannot remember who was teaching this at the Origami USA convention a few years back (2006? 2007?), but I seem to recall it was brought to New York by the Brazilian group. It was a huge hit because it holds models so nicely for gift giving.
Step 1: Assemble Parts
To start you will need:
1. Coke bottle of correct size (see Step 2 for selection process).
2. Sharp pair of scissors.
3. Rubber band (optional if you feel confident in your cutting precision).
4. Marker (also optional)
5. Fabulous gift to put in the container once it's complete.
