Thaks Mitty, that makes perfect sense. I am trying to decide how to quilt my quite large complex paper pieced Christmas image. Nearly all the seams are pressed open because that is the only way I can get the hundreds of tiny pieces to lie correctly and line up.
Now that SID is ruled out I think it will have to be be a very simple and almost invisible all over FMQ as straight lines wouldn’t look right.
I hate the quilting part of projects haha!
