This is such a fun pattern! Body and sleeve flies off the needles and all you long for is the yoke. Which was done in one evening.
I wanted a bit slimmer sleeves than the original sweater so I choose size 1 for sleeves and size 2 for body.
Body: Size 2. I made 7 lace pattern repeats before joining with sleeves. I’m 179 centimeters tall. Length came out perfect I think!
Sleeves: Size 1. Added rows until 7.5 lace repeats were done.
Joining sizes: If you make size 1 sleeves and size 2 body they will not be matching in lace pattern. But if you knit 1/2 chart less (or extra) on your sleeves they will match in pattern when you continue with the yoke. I made 7.5 lace chart repeats for sleeves and 7 repeats for body. If you feel unsure you can lay sleeves and body next to each other and see if lace pattern matches or not.
Yoke: I went for a lower yoke with only two rounds of flowers instead of three. Ended on row 36 on yoke chart. In my first row with color A I decreased like this: K2tog, k15 to end. Then followed pattern until bind off. I made no decreases at all on bind off row.
