Isn't it amazing how a purl stitch is really just a knit stitch done backwards? How the backside of the purl is the knit, and the backside of the knit is the purl? I've often wondered if in the beginning, all the knitters in the world were doing knit stitches only, then someone goofed and did the knit stitch backwards and revolutionized the way we all knit.
When you think about it that way, it decontructs all knitting to just one stitch, moving that stitch around and doing different things to it alone or in groups.
Knitting is more like tying your shoes than it is like patting your head and rubbing your tummy at the same time.
