I am a bit confused with your post. When you make a regular knit stitch the yarn is in the back, and when making a purl stitch the yarn is in the front. Maybe I'm just misunderstanding what you wrote.
Keep watching the videos and keep asking questions. Knitting can be confusing when you first start out, but before you know it, those needles will be flying and you'll be creating all sorts of wonderful things. Jeanie
