Learning the ropes

Knitting takes FOREVER. I've been working on the same scarf for over a week and it is maybe 2 feet long. Ay carumba-or something like that.
For those of you (and I don't know any who read this) that are trying to self teach and are looking at others blogs and whatnot, LYS means local yarn store (not to be confused with LDS, at first I thought 'Wow, is everyone who knits Mormon?). I still haven't figured out what FO is--best guess is finished object but I am not sure {perhaps Amy can advise?}. Frogging means you made a mistake somewhere, realized it later and went back and ripped out what you had completed to fix the mistake-frogging sucks, I have lots of experience with just this one scarf!
Have a goodie...
