I'd just SID quilted the whole quilt with it - no problem; it's a new (to me) machine I recently bought off a friend and I can't believe it's faulty; any ideas, anyone?
Did you change the length of the stitches? Sometimes, sewing through so many layers of material, the small stitches we use for piecing just cannot handle two layers of binding (+ the seam allowances when you hit them) + two layers of quilt/front and back (plus any seams you run into) and the batting on top of that! I lengthen my stitches from the 2 or 2.5 for piecing all the way up to 4 ...
