When slipping stitches purlwise or knitwise . . .
I understand which direction the needle is supposed to go, but where is the yarn supposed to be. For example, I know you can slip a stitch purlwise with yarn in back or slip it purlwise with yarn in front, and some directions will tell you to do one or the other. But when the directions don't say one way or the other, is there some default way they're assuming you know it to be?
