A looong time ago, a friends' nan showed me how to knit a basic scarf but darn (pun not intended!) if I haven't forgotten all about it. ^^;

I think with those kind of complicated hobbies it's really good if you can find a class/course or maybe just a friend or friend of a friend who wouldn't mind showing you how. Knitting seems too difficult to learn just by reading or watching instructional videos, or maybe that's just me being a dum-dum.
