I think it will be a personal decision on your part, if the magazine has the kind of articles and patterns that you like.
I've been getting Quilters Newsletter for a couple of years and ready to give it up. It has lots of what I call 'fancy, difficult' quilts that I like to look at but have no intention of ever making. I like quick, easy and many times scrappy quilts. So the magazine is a waste of money for me.
