Yup, Same here.. Ill use what I have, the top and bottom thread colors are are completely different in colors....

I've always wondered about this, and I'd like to know if anyone has ever tried it. What would happen if you just wound more thread onto the bobbin? I don't think this would work with an older machine, but my machine doesn't require that I even pull the bobbin thread to the top. When I rewind one, I just start sewing and it takes care of itself. So I wondered, would it just pick up the new end when it finished with what I had newly wound on? What do you think? One of these days I'm going to try it; but I thought if someone else already had, you could either encourage or discourage me from doing it.
