Thanks ckcowl and scrappy cats. I have changed the needles ....played with the tention all the regular stuff. And I have quilted many quilts on the frame, but this last quilt, which was nothing unusual as far as fabrics or thread was concerned was just an exercide in futility, so I pulled the 1/2 finished quilt off the frame and will try again on some practice thing when I calm down.
