What a quick project – I had this done in a week!
Yarn: Classic Elite Premiere, 5 skeins
Needles: 4.25 mm (the “larger” US 6)
Modifications: Moved the ribbing on the front up to the waist, and started the split for the neckline later since I didn’t plan to put buttons on it.
Details of modifications and more photos are on my Ravelry project page.
