The dishcloth pattern N0obKnitter linked to is a good one. It can make a dish/wash cloth or go bigger and make a triangle shawl or a square blanket. It's a good basic pattern to get acquainted with. I'm at that time suck ravelry.com right now looking for a pattern for a hat. They have tons of wash cloth patterns that can be made larger for whatever square or rectangular thing you want. There are scarves too, generally popular. Have a look around and see what catches your fancy, you can ask anything about it or for help here of course!
This is the last time I'm frogging this project for the last time.
