Thanks so much for all the input and suggestions. I've been on the phone with the dealer, and he wants to see for himself. He's pretty stumped, too. He says that I've tried most of what he would have suggested. He's 40 miles away, so I'll have to plan a Saturday to get it up there. In the meantime, I've got other suggestions from the wonderful quilters on this board. This is such a great group! Thanks, again.
