Quilters Newsletter Magazine has been around for several decades. I was a subscriber for many years. About ten years or so ago the original editor retired and the magazine changed quite a bit -- fewer how-to articles and more news about quilt happenings around the world. Their cover always features a spectacular quilt, but directions are not included; it's more to show what can be done rather than how to do it. Anyway, here is a link to their website:

Edit: The reason it's called "Quilter's Newsletter" is because when the original editor started it, she printed it herself in black and white. It was quite a few years before it went to color, and then it got bigger. I still miss her from the quilting scene; she had a remarkable eye for quilts.
