Phew, Baby Sophisticate all done! I used Cascade 128 from stash and the yardage ended up much tighter than expected. Also, I just validated all my yarn scrap hoarding impulses. I finished the sweater with 3 inches left of the white, and had to go fishing in my bin of random scraps to find enough odds and ends for the sleeves. This is definitely a one of a kind sweater! As much as playing yarn chicken can be stressful, working with constraints can really push us to come up with something completely unexpected.
Now to sew on the buttons and package it up!
