Can someone please tell me if I'm understanding this? I'm doing the Embossed Leaves sock pattern, and the chart calls for a yarn over before a purl stitch on row 2. Do I wrap the yarn around the needle an extra time since it's already in the front? Also, on row 10 there is a yarn over after a purl. Do I need to do anything special since the yarn's already in front? I've never done anything from a chart before, so this is all new to me. It's a good thing that the chart rows are numbered, because I would have started with the top row of the chart instead of the bottom. Is this standard for reading a chart? Thanks in advance for any help!
