OMGoodness,
I'm so sorry that this has happened and just when you need your machine the most! I hope that it isn't a costly and long protracted fix of the machine.
BTW what a great hubby to buy you such a wonderful gift!
I don't FM at all I'm getting the courage to try. My machine does not regulate the stitch length when doing FM quilting and my stitches are horrible, I know practice, practice, practice, practice....I will not ever use safety pins to baste reading about your accident. Now I will use the Sharon Schambers method that another quilter suggested!
