It seems like lately everything is called poncho or kimono. I don't see how this is anything but a vest. Certainly a long, cozy one, and one with shoulders that drop down low, but a vest nonetheless.
I made a poncho!
I knit this poncho using wool that I purchased with no pattern and no plan. This may not sound like a big deal if you have not knit before, but buying yarn with no plan usually just leads to a closet full of pretty yarn, rather than a closet full of pretty sweaters.
