I have the octi hoops and I am having a problem. After stitching a 1 or two the upper thread no longer grabs the bobbin thread. I have re-threaded, cleaned changed needles.... I haven't been able to buy the books or the dvd , but have watched all the videos that are out there. Anyone know what my problem is. I would appreciate help and would even be willing to call you on my dime. Help please. Thanks a bikkion.
