Gerry is right, it might stitch out OK, especially when it's an outline, but it's not the same shine and I would not do it. I have however used an almost black (very very dark blue or grey) instead.
I know it's better to use embroidery thread, but I'have used sewing thread some times or bobbin thread.make sure the thread is thin.But the result is not so nice as embr.thread.
