I'd buy a lot (more) yarn and travel to places just to sit and crochet or knit with it. (probably buy local yarns made wherever I'd travel)

Or, I might start my own yarn store.

I'd buy myself a house.

I'd buy my sister a house. I'd also set her kids up with college money (and living expenses so they wouldnt have to worry about that when they go to college) I'd probably also pay for private school now...and the special programs that one of my nieces is in because she has (high functioning) Aspbergers. (autism)

I'd also try to save a friend's business if they'd let me do it.
