Hi RondaK When I am embroidering the panel, through experience, I skip the second tack down, and the inner stitch lines now, this doesn't mean anyone else should. I found that they get in the way when piecing and get in the way when making adjustments, assembling parts together (wiggle room), much easier to adjust on the fly, sometimes they can bunch up and misalign lines. The next job is to stipple the back with the same stipple pattern as used behind the front embroidery panels
here are the rest of the panels
