You can learn both knitting and crocheting 'easily' (being relative)from a good book. Look for one with lots of pictures!! But YouTube also puts out a ton videos on how to crochet or knit. For knitting though I would suggest finding a cast-on tutorial that works for you, there are a multitude of ways to start your knit and really the most confusing part in knitting is getting stitches on the needles. Once you figure that out, everything else is easy.
