In one sentence, describe what the following article is about:

Your cookie dough needs to be log shaped so it's thin enough to fit into the barrel of the cookie press. To roll the dough into a log, pick it up and roll it between your hands. Make sure the log is short enough and thin enough to fit in the cookie press barrel.  To save time, buy premade cookie dough that comes in a log shape. Avoid using cookie dough that has big pieces like chocolate chips or nuts in it. Use thin doughs like sugar cookie dough and spritz dough instead. Make sure the ring is twisted all the way on so it's tight. If the ring is on properly, the patterned disk will be on the inside of the barrel. Once the ring is on the barrel, you're ready to start pressing out your cookie dough!
Roll your cookie dough into a log. Screw the ring back onto the barrel.
