I finally finished my Cornsilk sweater, knit in Classic Elite Classic One Fifty yarn (now discontinued) and just love the way it turned out! Not only did the fit come out better than I'd hoped, it's warm and cozy, without a hint of scratchiness. I've worn it almost every day since it came off the blocking board.
I made a lot of tweaks -- using a different gauge yarn, fine tuning the fit, and construction adjustments (just cause I like doing things a certain way to make the final product more finished looking). See page one of about four pages of notes, plus spreadsheet. But it was all worth it.
And.....I used 1275 yards of stash yarn. Double bonus!!
