I lilke to place the pins about every other "arch" piece. I prefer to do Continuous Curve quilting on the pieced arches of the DWR. I have authored a book, Continuous Curve Quilting for the Double Wedding Ring Quilt that details the stitching "pathways" of CC on the DWR quilt. This book is avaialble via the Longarm University website www.longarmuniversity.com
