Sorry best thing as all replies is to take the stitching out, I had this prob when I first fmq'd, and after watching u tube from missouri star, I realised I was using my auto tension button, and this was causing the issue. MS video recommended setting tension at 8 (they were using a janome, which is what I have) after I set my tension at 8, I still had the odd wee loop but not the whole thing looping which was what it was doing previously, hope you get your quilt sorted
