I want to recommend this shop: Atelier Puupuu

I placed my order Jan 14th, and I just got my package from Japan. :) I ordered 8 diagrams, but they also sent me an extra diagram, plus a bunch of gorgeous paper in different sizes/colours!

The diagrams are well-drawn and detailed, plus in colour. The english isn't perfect, but as long as you can follow the pictures you'll be fine.

You can expect some more kusudama submissions from me in the near future. X3

I also recently bought the book "Modular Origami Polyhedra" a few days ago, and I'm not really happy with it. All black & white, and either I am missing something or they really aren't clear about how to assemble all the pieces. I think the instructions are really unclear in general. :B If you're going to do B&W diagrams, it should at least be made clear with grey shading which side of the paper you're working with. Just a really cheap feel to the whole book.

Also I would kill to find the diagram to this: http://www.flickr.com/photos/989632.....N04/1216249551
Can't find it anywhere.
