Paper Source - Flower Puff Ball Window Display

I found this flower puff ball in the window of Paper Source one evening.  It was surrounded by the tissue paper puff ball ornaments found everywhere for the last few years so it really stood out from the crowd. 

I find paper folding calming so I think this would be fun to make and after thinking about it I realized I pinned instructions on how to make it a while ago.  There is a tutorial on how to make the Kusudama origami flowers on the Folding Trees website.  The instructions on how to attach them to make a ball or ornament is here.  It actually looks like a lot of fun!

Has anyone ever made these?  I'm thinking they might be fun to make for the holidays or perhaps if the power goes out with the storm today.
