Just over a year, start to finish, including 10 months in time out.
I picked the wrong size to knit, since this was well before Amy's fit to flatter advice. I knit this at my bust size, instead of my upper bust (higher than the boobs and under the armpits) so there's way too much ease. I may still mattress stitch up the sides above my waist to try and pull it in a bit.
The fabric is great though, nice and drapey. It's nice to have a sweater that can be worn right next to my skin. Take THAT peruvian wool!
I also skipped the lozenge pattern on my version. When I cast on we were right in the middle of the first round of book edits on Knitting it Old School and there's no way my brain could have handled it. I needed mucho stockinette.
