If you are following a pattern, then cast on the number of stitches that the pattern specifies. If you just want to practice the knit stitch, then cast on 10 stitches.
When working the knit stitch, it is important to always go in through the back of the stitch.
If you are right handed, then you will loop the yarn around counterclockwise. If you are left handed, then you will loop the yarn around clockwise.
Be careful as you slid off the cast on stitch. Make sure that only the stitch that you knit into comes off.
If you want to determine the number of stitches to cast on, make a one-inch square practice piece. The number of stitches depends on the size of the yarn. It also depends on the tension, or how tight or loose the stitches are when you knit.
