Most of the magazines that I like are by Fons & Porter, though I seldom buy them anymore. I loved Quilty and made a quilt for my son with a pattern from that magazine, but it's been discontinued. Looking back through my small stack, I have several issues of Easy Quilt and a couple of issues of Quilting Quickly, but never made anything from them.
About the only reason I buy or keep magazines now is if they cover a technique that I want to learn (got WAY more patterns than I'll ever use), and I usually look through the quilting books and magazines in our library's used book store, where I can buy them for a quarter a piece.
I bought one issue of Block and I really like it, but with so many MSQC tutorials online, I don't see a need to buy more.
