Aww he's so cute! I love the color. It looks very aquatic.
My first crochet was an octopus too! I found crocheting about 10 times easier than knitting. I tried knitting first, but I didn't really get it, so I went to crochet instead. Eventually I tried knitting again, and it was easier the second time around.
Maybe you could try it again. Try looking for knitting tuts on youtube or something.
