It really depends what your preferences are. Good idea, to check some out at the library.
I've at various times subscribed to Fons & Porter's Love of Quilting, BH&G American Patchwork & Quilting, Quiltmania, and Today's Quilter. Of those, American Patchwork & Quilting had the most patterns I was interested in. When I began quilting I wasn't sure of my direction, but I am definitely now more interested in traditional than modern quilting, and they had the most of what I would call 'traditional' patterns, although one of the Fons & Porter ladies features a traditional quilt in each issue.
