i have found the most helpful resource for quilting techniques to be The Better Homes and Gardens Complete Guide to Quilting. I bought the hard cover spiral edition in 2002 and have used it as a reference for every quilt I've made. It has a section for every area and technique of quilting. I have found it especially helpful for guidance in sizing and piecing quilt backs (and hanging sleeves) as well as quilt binding. Not much in patterns but handy when I forget how to join the ends of binding when sewing it on the quilt.
