How do you make a dreamcatcher?

Okay, so, there’s plenty of instructions floating around on the web, but I’m not quite sure about which ones to follow. Most seem rather “simple”, like metal ring and plastic feathers. I want the real deal though, it’s for someone really special. So, the bigger the better, possibly like the one in the movie Dreamcatcher. I could buy one, but that’s not “special” enough, this one has to work! Any experience you can share appreciated. Like, what kind of feathers should I use and whatnot.
