hemming the short length

I am one of those people who is SO short I have to hem even the short length pants I purchase. Well despite all the sewing I've been doing the past year +, I've always been so afraid to try to hem my own pants. Partially because it's hard to measure them on yourself, partially because I'm afraid of screwing up and wasting a pricey pair of pants. Well, I finally took the plunge and I think they turned out pretty ok.... They seem a little short, but they're a very wide legged pant so I might be fooled by the "airyness" I'm feeling....
