The darn book won't stay open!

I'm determined to learn all the buttons on my Canon camera.  The manual is okay to understand, but print is way too tiny for my aged eyes, and it won't stay open.  I  downloaded a copy from Canon that's easier to read on screen, but it's a bit of a pain when I want to lounge on the couch and read from the coffee table (in my case tea-cup table!) with the camera on my lap.  Printing pages was fine but with too many to print, I decided to purchase a Canon 7d Guide from Amazon.  The book is great, but the pages still wouldn't open flat.  I was just going to get it "spiral wire bound" from Staples, but found this guide for opening new books correctly and it really works to keep them open!

I love how this guide has been illustrated:    guide
