--> Increased lace portion to 9 repeats = 10 st from armhole (smallest size: 7repeats=8 st from armhole.)

in order to synchronize neck shaping with 8 lace repeats (1smaller than largest) biased bind-off:6/6/6/4/4/4, thus binding off four more stitches. will be ok for I want ribbed neck band anyway.
steek st stopped with beginning of neck shaping, after that finishing separately.

No way the pattern asks for 22mm buttons. My buttons are 20mm and way bigger than any I have seen so far on any foto…-->need wider button bands (40 mm)

Had to re-knit button bands. Did this by knitting them seperately and sewing them on, because fabric was already rather stressed from knitting-on and ripping-out again. Reinforced button bands on the back side with grossgrain ribbon, at the same time hiding away steeks. Added plastic snaps, “real” buttons are just sewn on for decorative purposes. (No buttonholes, no stress)

January 24th, 2013: first sleeve finished with tubular cast-off sleeve tight but hopefully not too tight. For full length sleeves added 60 rounds of stockinette after final decrease, then 40 rounds of twisted rib with smaller needle (!)( 2,75 mm), then tubular bind-off as described in the link.

This took me just over two months to finish (including several re-dos).
The yarn shrinked quite a bit length-wise after blocking, such that sleeves are a bit short for my taste. Should have measured the swatch after washing… ahem.
Still, even though arms are very tight I like the overall fit very much. Beautiful, well written pattern.
