Simply clip into your hairstyle anywhere you like.  (Behind the ear is nice, if wearing your hair loose.)  For added staying power, tease or backcomb a small portion of hair and give it a shot of hairspray before attaching your hair extension.  Got super-fine hair?  Take a small section of hair, braid about an inch and secure by tying with a small hair elastic.  This can be left in for several washings and provides a secure anchor for your extension.
