I need help with my Janome 6700
I bought a Janome 6700 in July and I've had an issue with it not wanting to go over thicker seams in my quilts. It bogs down at those seams and sews very tiny stitches and I have to "help" it to go through them. What do I need to adjust? I've never had a problem with my Brother machines. I've been sewing with the default pressure foot setting from the factory set at "3" and I've moved it to almost "2" but it doesn't make any difference. What else can I do?
