I am a big fan of Amber's (Darling Diapers) patterns. I have purchased the AIO, potty dance pants, and bib patterns and they are all excellent.
She also has a pocket fitted pattern that I have heard is very good and easy to transform into a plain fitted or a true pocket.
Oh, and if you email her (address on the web site) and ask, she'll send you a copy of her free newborn-size fitted. No instructions, but a cute one to serge. Here's the link to the original discussion to it... and I just bumped it, too.
