I was asked to quilt a quilt for a the mother of a friend and I agreed. It was delivered to me the other day BUT I was not informed that she had already sandwiched and sprayed basted the top, batting and backing. She was planning to do it herself. What am I suppose to do? I have a home system with a Janome. Eventually I would be quilting through all three layers so I am wondering I can leave it sandwiched, load onto the front bar and quilt as normal. Hope this makes sense. Has anyone ever tried quilting this way?
