I have now successfully finished my first adult sweater in recent years. The sweater is Mayan Puzzle by Anne Hanson at KnitSpot. The yarn is from the KnitSpot yarn company, Bare Naked Wools. It is Kent DK in the color Tide Pool.
I really like the finished sweater and even managed to get it sewed up and buttons on it fairly quickly after I finished the knitting. I'm unhappy that within three or four wearings the sleeves have started pilling along the underside of the arms, where they rub against the body. It's a brand new sweater that already is starting to look raggedy. I will definitely think twice about using this yarn on another project.
