Anyone good at tying a sari?

I want to wear one soon, but need to know if it's difficult? I've only worn one a couple times but this time I'll have no one to help me. Can anyone suggest anything that might make it easier? I know they have pre-tied ones now but the one I have isn't.

I want the type where it drapes from the front to the back (pallu I think it's called) and a little bit of the midsection showing.
