What I folded last Christmas

 Last Christmas I finally decided that this was the year I was going to implement an idea I had had for a few years.  A year or two previously I had tried it in another cubicle but I was sitting with bah humbugs. This particular year I was with more amenable people.  This was the year of the origami decorations:

Magazine Christmas Trees

I went for coffee one day and when I came back two more had sprang up!

Honestly, of all the things I did this was the most infectious.

Five pointed star - but first you need to fold yourself a regular pentagon.

This is not strictly origami, possibly more kirigami. 3D Snowflake.

Further origami Christmas ornaments: A simple ornament, via the origami resource center.

(oh yeah - we won some very tasty "fruit juice" which was appreciated in the last scrum of the year)
