There's no such thing as a stupid question. We've all been raw beginners like you at one time. We asked stupid questions, too, or were so embarrassed to ask that we had to figure it out for ourselves. Much of what we know has been from experience and making a lot of mistakes. So you're not alone. As to the right side, wrong side thing. Look at your tail. Yes, I know, Susie. Sometimes the directions are different. But GENERALLY, your tail will be on the right side of your work for right side rows and on the left side of your work for wrong side rows. If you are following a pattern, your odd numbered rows will be the right side and your even numbered rows will be the wrong side. Pay attention when you see directions such as yours which say, ending on a wrong side row. This usually means that they're going to have you do something different on the next row. If it's increasing, decreasing, cabling, or anything like that, it will usually be done on a right side row. When it says Ending on a WS row, it means that you will knit or purl (depending on which stitch your pattern calls for) that entire wrong side row before doing something different on the next right side one.
