It really does make the job easier and I have used it in the past and love it. But someone suggested to me that it could void the warrantee on my machine. So I contacted Bernina and yes, indeed, they did confirm that. I also wrote to the Glad folks and they also said that it wasn't meant to be used with a sewing machine. Just thought I'd pass the info along - I still love the stuff but won't use it with my machine any more.
