Magic ring completely stumped me for a long time. Here's the guide that finally helped me "get" it:http://www.craftsy.com/blog/2013/09/demystifying-the-magic-ring/
Honestly, I think most of the instructions for magic ring get way too complicated in their description of how you hold everything. What you basically just need to do is create a loop of yarn that you first pull one stitch through, and then just create however many single crochets you need. Then just pull it tight.
