How do I turn my knitting so that the right side is facing me?

Look at the fabric. One side will be prettier than the other. That's the right side. If you are looking at stockinette knitting, where you knit one side and purl the other side, generally the knit side is the right side. Examine the stitches. On one side the stitches look like the letter "V." On the other, they look like bumps or dashes ("-"). The "V" side is the knit, or right side, and the "-" side is the purl or wrong side.
