Done and done, just in time for the first 90-degree day of the year. This pattern is the Gooseberry Cardigan from Interweave Knits Weekend 2009 issue. I made the 48" size and used 13 skeins of Knit Picks Merino Style, which is DK weight, in Fairy Tale.
It took an eternity to block, but it was well worth the effort to get the collar to lie flat. I really like the oversized collar and the long ribbing at the bottom, but think I may have been better off knitting a smaller size for the sleeves, as they seem to bulge under the arms.
