both good questions! To which I do not know the answer!
Ya'll are really good. After a week of frustration working on this quilt a little at a time (I have 2 jobs that do not involve quilting) I finally posted for help. ince then the last 3 blocks I've been around have been great. I think it's the drag, pull, weight of the quilt - and the learning curve involved with a new machine. But ... if it starts up again I'll get the answers to Prism99's questions.
