I like having my early projects which were ponchos (free patterns from Lionbrand). It's nice to have it be tough enough so I'm not worrying about any little snag, like when the dogs are all over me, etc.
You can see them on my Ravelry page and search for "poncho", they'll come right up, or just scroll to the early FOs.
It's also always nice to have some scarves and hats lying around you don't mind giving away to a visitor if they need one. Quick, easy projects.
