[COLOR=DarkOrchid][SIZE=3][FONT=Comic Sans MS]Crochet is often reversible because it's a back and forth thing like garter stitch in knitting.
However, with that said, if you crochet a small square and pick one side to be the public side, and with a different color, crochet a row of single crochet around it, you'll see that the border on the public side is different than it appears on the private side. Mainly in how the colors of the square show through the single crochet border.
Your chain row is not a row. When you turn and crochet back, that row as it faces you while crocheting is the first row of the public side. Mark it so you know, and as you work on your project study how the sts look on the public side vs the private side. You will see a difference and being able to spot it will help you later on in your crochet. Such as when you do a bunch of granny squares and want to crochet them together, you will be able to see which is considered the public and which is the private so they all match and are displayed correctly so your MIL doesn't come over and tell you it's all backwards!:lol:
It's a minor point when you are first learning the mechanics of crochet but later becomes more important, so it's good to know. IMHO
