i started this in april, and the custom-plied silk from habu textiles was very pleasant to knit. the shawl collar, according to vogue knitting, should have been accomplished with one simple, long rectangle; but i think, in part due to the unyielding nature of the silk, we had to go with some short rows when we were nearly finished.
ben says it's very comfortable. we're figuring the waist and cuffs will "ride down with wear", as mr. humphries would say. (but in the case of a silk sweater, it should be true.)
