Some advice please.....This is the first time I have had this problem. This is the first time that I have totally pieced both the front and back of a quilt and it is for a gift for my cousin who is due in November. I have been FMQ this in quarters...on the very last quarter this is what I get on the underside (bobbin side). I did not change my settings. Can anyone please tell me what I am doing wrong???? I am now un-quilting this section...Please help, I am desperate.
