Thanks for the recommendation. I've been hoping to find time to whip up some basic t-shirts and learn how to make them fit right, just hadn't settled on a pattern. But free is a big attraction to me right now so this might just be the one :D
I like Plantain too! If you are on the lookout for free patterns (aren't we all?), the Core T-Shirt by Closet Core Patterns might also be something to look at. It's a boxy fit, though, so not really an alternative to the Plantain.
