Perfect! Thanks for helping me to understand it.
One other question. It seems like in patterns (although I am only using them to learn since I want to make up my own stuff), they say to join and then chain stitch at the end of each round. I have tried that, and I have done things without doing that. It seems to look better without doing that. Am I doing something wrong then when I follow the directions?
What would be the reason for joining each round rather than just keep going?
