I recently learned to knit and I am trying desperately to teach myself to purl. I think I am doing it correctly but the problem is that my knit stitches don't look like v's. Now I'm worried that I'm doing my knit stitches wrong. What stitch is supposed to look like a v and how do I do it? What is the basic difference between what a knit stitch looks like and what a purl stitch looks like? I'm so confused

Thanks for any help you can give.
