itching for a sweater

I have been ITCHING to knit a new sweater for myself, something for the fall/winter. I have been itching to do so for a few months and I think it's finally got to a point where if I don't buy yarn and cast on a sweater for myself I might start convulsing or frothing or...I don't know what. I would ask what is wrong with me, but I know you'll all just say "nothing". :D

There are a million sweaters I want to make. I need to decide on just the right one. Off to search.
