When you knit a chart on a flat piece of work, you read the right side from right to left and the wrong side from left to right.
The meaning of the stitch does depend on what side you're on. If you're on the wrong side, you do it the way it says, and if you're on the right side, you do it that way.
The best way to keep track of your rows is to put a post-it note right above the row you're doing. This allows you to read your row across.
Usually odd rows are the front and even rows are the back.
