I've been working on the sweater yoke, and I'm now halfway there in the decreases. I have 30 decrease rows to work every other row (meaning 60 rows total), and I'm now on row 30. 30 more to go.
Anyway, I was thinking about the math. When I joined the sleeves to the body of the sweater, I had 354 stitches on that round. So far I have worked 2 decrease rows before the set of the 30, and 15 of those rows. Thus, a total of 17 decrease rows with 8 stitches each row. I have decreased the yoke by 136 stitches, leaving me a total right now of 218. Admittedly, I would have to work up a quick Excel spreadsheet to actually calculate how many stitches I've been working each evening, but seeing the numbers helps me reconcile why this is taking so long!
The really sick part? I think I'm starting on another sweater when I get finished with this one. I have a LOT of sweater yarn, and I'm thinking I need another one for me.
