I’m a very new knitter trying to make a baby blanket. The directions say it’s an easy knit baby blanket, but I’m stuck. I think I know what a yarn over is, but the directions ask me to work through the back to twist the stitch so the holes are smaller. How do I do this? I’m totally confused and would love to have this blanket done by next month. I bought a $20.00 DVD, but wouldn’t you know it didn’t even have how to do a yarn over on it! HELP!!
