Well, I am the odd quilter here. My favorite is American Patchwork and Quilting. It has quilts for every level, quilting tips, etc and I love the semi annual Quilt Sampler magazine they do.
I have also subscribed to Quilter's Newsletter Magazine and Fons and Porter. I like both of them too, but just do not have the time to read that many magazines and they were taking over the shelves.
