Needles:
Have no 3mm needletips, so I started a sample with 3,25mm.
Made a swatch with 3mm: it seems to match the gauge unwashed.

2.5mm: ribbing sleeves, collr/neck
3.0mm: body stocking stitch
3.5mm: lace parts

Start:
After the picking up stitches from collar I reknit the increases section 2 times. My increases in the back and on shoulders looked ugly. Finally increases from stitch in below row worked best for me. Very neat look, I really like it.

Finish:
Knitting & wash done.
Added 3 small buttons for wearing it closed.

By wearing the sleeves stretch out a lot in leghth and sides. I want to reknit them more tight. I would also reduce pattern repeats in sleves to same number as knitted in body… I think this looks nice, just like a pattern block across the piece.

I would rather use a 100% wool fibre instead this cotton-wool-blend. I feel the cotton stretches out too much for my taste.
