Or, your short arm quilting machine keeps breaking the top thread. You try everying for hours. Finally give up and wait for the weekend to drive 90 miles one way to take it to the shop. Have to wait two weeks to drive another 90 miles each way to pick it up to only have the tech tell you there is nothing wrong with it. Take it home, ask next door neighbor's husband to remount it on the frame and the first row it is breaking thread again. Finally decide to change thread manufacturer and it works perfect. . . . . except that the color is off just enough to be noticeable. Luckily it is a baby quilt with flannel on both sides, so it might hide the thread.
