This is my top-down sweater's work shop. It is raglan shape, and seamless with just few weave in end threads. I have made a top-down blouse with circular yoke for my sister, and I have made this one for me.
I have used thread size 20, and steel crochet hook size 8. I have modified the pattern to suit my size.
This pattern is Japanese chart from book called "Top down crochet".
