Sleeves worked flat.
The pattern was a pleasure to knit. The only tricky thing was to fit the lace pattern to the raglan and front neck. I had to do the yoke twice before I was happy with it. After ripping I decided to omit the two knitted stitches between each pair of raglan decreases, and knit as many lace stitches into the raglan and front as possible.
Buttonband: added 6 extra sts to the front neck edges and 2 sts to the back edge.
Weights exactly 250 grams without buttons.
