I considered doing a Continuous Curve quilt line over the pinwheels, but I could see that the quilt's seams did not always meet exactly. Continuous Curve would only have made that situation worse by highlighting the missed joins. So, I suggested quilting down the background, leaving the colored triangles unquilted. What awesome texture appears! She was quite thrilled to see this little piece finished, which she had originally basted for hand-quilting --- that she knew she would never get to. Sweet! Just love it when a piece gets finished that may have sat in a closet until who-knows-when!
