As a long arm quilter doing work for other people I give them an estimated delivery date when we go over the details. Also, their names go into the my que as soon as we agree that I will do the job. If I have a wait the person hangs onto their quilt until I am ready to start on it as I get closer to their order, usually two quilts out, I ask that they get me their project and we go over everything one more time to make sure nothing has changed from the original plan.
