Needle in correct? Be sure your bobbin is not in upside down and turning the wrong way. Possibly the hook that the bobbicase fits in/on has been hit by a needle and caused a burr that is catching the thread as it comes around. The burr would have to be polished off or hook replaced. The machine could be slightly out of time also.

Hi Diane...you can wind bobbins while you are sewing your product, or you can wind them seperately. To wind them seperately, pull out the bobbin case, lift the presser feet up and lock them in the up position, undo the threading beyond the tension assembly. The takeup will create a birdsnest if you don;t pull the thread from it. Wind your bobbins, the re-thread your machine, insert your bobbin case, drop the presser feet, pick up the bobbin thread and sew away. If you need any other input, call me at 888-283-9640.

did you get the needle in correctly--all the way up into the needle holder
& the flat side of the needle goes to the back of the machine
also after you check the needle & it's in correctly it's very possible that the machine is out of time & a sewing machine repair technican would have to retime the machine
