Boy, I hope someone out there can help. I am trying to zigzag an applique with invisible thread. Is it possible? I am using that as my top thread and regular thread in the bobbin. The thread does not pick up the bobbin thread. It will be great for about 10 stitches and then skips all over. I have a Viking Designer II and tension is built in. I have threaded and re-threaded several times. Any other clues to success? Thank you, Lynne
