It took 8 skeins of chunky weight Lamb's Pride wool (85% wool, 15% mohair). And after all that knitting and pattern revision, I ended up with only 27 inches of leftover yarn. That is right living.
See that yarn? That is the 27 inch left-over tail end from the 8th skein. (Mug by Jenny the Potter.)
It was a bit large, so I threw it into the dryer while it was still damp from water blocking. That helped it come down a bit to size, but the front of the sweater has an uneven edge, likely because I have no chest!
Revision details can be found on Ravelry here. I would knit this up again sometime, but it will be a long sometime before I do it again due to the bulkiness of the project.
