sewing machines are moody little cusses, aren't they? mine will zip along just fine through point tips, backward pressed seams ... you name it. but, just as it has lulled me into a false sense of blissful security ... WHAM!!! big blobs of chewed up whatever. drives me nuts. :roll:
try putting little bits of paper torn from your junk mail under those intersections. save a tree ... and your mind. :wink:
