I'm about to knit some longies, but these are by the same woman
Vanilla Soaker
I would recommend joining Ravelry, and searching the patterns for something that looks like what you are after. Some of the patterns are free, and some of them you pay for.
And if you ever find you don't know what to do, Y*u T*be has lots of video tutorials, thats how I learnt some of the more tricky techniques.
