At first you start with making a swatch to measure and decide the pattern gauge. Then we use basic calculation to know stitch and row numbers for your size. To make these process easier, this pattern took a workbook style.
Maybe you feel not comfortable with Ripple stitch in this pattern at first. If so, Sazanami Socks free pattern will be a good practice.

Also, I made Mini sweater full pattern at the end of this workbook. It will help you to understand the construction of this garment.
This pattern has released in Japanese in last April, and I translated it into English. I'm not native in English, so I also need grammatical corrections, not only technical feedbacks.
Honestly I'm not sure whether Sazanami Sweater of Ripple Pull is the best naming for English pattern. I'm glad if you tell me your advice.
