I am absolutely obsessed with this top and I'm desperately trying to find out the original yarn.
For those of you who asked, the book is called Elegance Knits, Let's knit series 11 and it's listed on this page, on the right side, where all the other books are, - with links in Amazon JP and YesAsia.
Here are the requirements
hopefully somebody will help me translate this.
Up to now I've tried Rowan 4 ply soft - too thin, Zarina - didn't like the twist in the twisted stitches, Debbie Bliss cotton blend - too splitty... call me fussy, but I need to get this right as I will be probably knitting it for the rest of my life :).
