May not look as pretty, but at least I don't break expensive needles!
i had the same problem. found out it was the invisible thread i was trying to use. they worked fine on regular thread but the invisible would break needles and mess up on the back. so i just use a regular needle and sew each side if i must use the invisible. on anything i can match, i will use regular sewing thread.
