I finished a quilt for new baby. I machine quilted 1/4 inside most seams (like if I would have done if hand Quilted). So I have LOTS of start and stops! I read that the stitches should be tied on back. Well that's what I did on over half start and stops. Now I find some are coming out, like all the handling while quilting. The stitches that are coming out at ends are in a rectangle where I started stitching and no other stitches join. No problem when the stitching joinsand either gets close or overlaps the begining. I think I need to go over the ends again if the rectangles that are coming out
