Once you get started, you'll find out that a lot of people you know knit and you never knew it too. They'll be helpful (probably to varying degrees) as well. No matter what you run into, there's SOMEBODY out there who's run into the same thing, and gotten it sorted.
As Mary, the owner of the LYS here, always says "It's knitting, not rocket science." And if there's anybody who's sorted more knitting problems than Mary, I don't know who that person would be.
