My machine works fine(Singer 403) doing a couple of layers of Momentum. But I'm trying to close the edges of a Top Quilt and it keeps breaking the top thread. A pleat on two hemmed seams makes 8(I think.) layers of fabric. While that seems(haha) like a lot, this machine will supposedly do multiple layers of leather, so relatively speaking, this shouldn't be that tough for it.
Is this a tension thing? I usually run with my top tension near minimum 'cause that's what it likes and what gives me a well balanced stitch.
I've changed needles and run other material fine, but when I put this in, it only makes half a dozen or so stitches then breaks the top thread.
What do you think?
