What you are doing right now (which looks GREAT...nice and EVEN!) is called "Garter Stitch". This happens when you knit BOTH SIDES of your work, because the back side of a knit stitch IS a purl stitch. If you knit the front and purl the back ("Stockinette stitch"), you will have a bunch of V's instead of V's alternating with bumps. Stockinette will give you the knit-looking fabric that you are familiar with.
Keep watching Amy's videos! You're doing a great job!
