Have you ever been working on a new project, and the farther you go, the less and less the project looks like the picture?  It could be because you have a pattern written in UK terminology.  

How do I know if it’s written in UK terms?

One way to tell is if you see the term “single crochet (sc)”  British patterns don’t contain the term “single crochet (sc)”.
