This video describes how to fold a fantastic star "Helena" designed by Carmen Sprung. You can use it as a case or wrapper for a CD or DVD, too! Carmen kindly gave me permission to make this video accessible to you.
Diagrams can be found in the book "Origami: 21 Sterne" by Carmen Sprung: http://www.happyfolding.com/book-spru... While the book is in German, it was proofread (or rather: test-folded) by a folder that knows no German, and he had no problems with folding the models from the very clear diagrams. So even if you don't know German, this is a fantastic book to get. It may well be the most beautiful origami book I have!
