My favorite is whatever one I can get my hands on here.
The "bookstore" and I put it in quotes because to me, it's not really a book store. Yes, they sell books, but mainly have ones that are a few years old and it takes alot of time to get a new one ordered from them.
The Navy Exchange here does sell quilt magazines, but only 3 of them and they only get 5 copies of each. UGH!
