All you need is one sheet of paper and one cd for size purposes (no glue/cello tape/scissors involved!)
Sorry for the bad quality images, but my 8 megapixel camera is broken, so I am using my Motorola L6, which is modded by the way!
Step 1: Measurement and first fold
2. Place a CD on the left edge in the middle (see pictures for better description)
3. Fold Edges over so they partially cover the cd (see second picture for better description)
4. Flatten folds
