This video discusses why you would stitch-in-the-ditch on a quilt and when it may be best not to. I show the advantages of both on my second Improved 9-patch Quilt.
Thank you. Quilting a large quilt with a graph patching pattern. It seemed a little over kill to stitch in the ditch in all lines, then stitching through seams again with quilting. I Also have less puckering on backside without all those stitch in the D lines.
Your dimensional example was dramatic and really enhanced the patterns and motion of your quilt. I will stitch in the ditch which is easy for me AND to add more texture will make the quilt pop!.
