Ummm patience and persistence is really where to start. :|b it's easiest if someone teaches you in person, but online videos aren't a bad method (they're how I learned). Just buy some cheap needles and yarn and plan on your first "scarf" being completely unwearable. xD You can unravel the yarn afterwards and reuse it to make a non-horrible scarf once you have a grip on what you're doing.

I use it quite a bit because all of my friends do. XD So that's how I got roped into that!

I keep wondering - what country are you from, exactly? LOL And I have several friends that love ketchup. I just put some space between us when we eat, and it's fine. xD
