There's several patterns with pockets. There's one in Folk Shawls, others in Vogue Knitting on the Go, 24 hour Knitting projects, one in Knitter's Magazine 69, Winter 2002 which is also in Scarves, a Knitters Dozen., and I found one here - http://www.lisaknits.com/misc.html
though I'm not sure how to get the pattern. Most of the book should be able to be found in a library, or requested on loan. I think there's one in an old Reader's Digest Book of patterns too.
