Let me start by saying...I have a Janome 1600 series machine a Grace frame and wanted to improve the quality of my stitches so DH bought me a surestitch from a dealer I thought that was so sweet! Well guess what no matter what it is set on it just stitches tiny little stitches or my thread breaks or better yet skips bunches of stitches that seamed to look okay at first! Well I adjusted Tension til I am blue, rethreaded and just want to give up! I did contact dealer that said maybe the little blue box is malfunctioning! But are is there anyone that has used this surestitch that could give advise before I jump off the deep end screaming? HELP. Thanks for letting me vent. Jan
