First of all welcome to the QB from SE Michigan. I have never heard of Omni stitch??? I just did a quick look and did not find much of anything. I figure it is and embellishing tool of some sort but I did not even find a picture of one. There are manuals available on ebay for one that was about it. I wish I could help you more on this one it sounds intriguing. Again welcome to the QB and please jump in and join the fun even if it appears that no one seems to have an answer for this one. Thanks again for the question.
