Twelve weight thread is the biggest that you can safely use on your machine. In order to do this well, you may have to adjust a few things.

Vanessa does an excellent job explaining what you should adjust and she even explains why, which is nice because that way you are not just taking a chance on a tip that has no reason.

This video is great for anyone, but especially beginners because it covers something that may not be very widely known, even by an expert.

The first tip that Vanessa gives us is that we must switch our needle from what you usually use to a needle that is at least 90/14.

Next, she says that it is also a good idea to use a fifty weight thread in the bobbin, which may take you off guard but Vanessa will explain.

Fifty weight is thread that is pretty usual. The third tip is that you should loosen your top thread tension.

Her fourth tip is to lower the stitch speed and the fifth tip is simply to experiment. There is so much more information in the video so check it out and experiment with that twelve weight cotton thread.
