clothing help

Anyone out there know any good sewing tricks for clothing alterations? I've got a nice pair of trousers (not jeans) that are just too damn long, because I'm short and it's incredibly difficult for me to find pants that actually fit and they all wind up being too long. I want to shorten them a few inches without, y'know, making them look shitty. Advice? I'd rather not have to hunt down and pay for someone else to do this for me.
