What does single crochet increase mean?

How do you stop a crochet increase?

Use the guide above as a general rule of thumb. Check the width of your beanie after every round. When you get the crown of the hat about as wide as suggested, simply stop increasing. If you stop increasing at 6″ and have 50 sts in that round, you would continue making 50 st rows until you reach the desired length.
