I used extra-fine merino, double knitting weight, from ColourMart. I've sung the praises of the yarn from this UK vendor before. They are like a knitting yarn jobber - they reformat fine machine knitting yarns used in top knitting mills in the UK and Europe into weights that hand knitters can cope with. (I'm wearing the cardi with a silk top also from ColourMart yarn.)
It does fit, as you can see. The shoulders are dropped but not excessively so. I made something between the smallest and second-smallest size and it seems about right.
The fabric is stretchy and could be pinned together at CF, if I was so inclined.
I like the simple zig-zag lace - it was very easy to memorize the pattern.
To the right you can see how the sweater is constructed, from the inside. The horizontal line is where the back joins the front and lower edge of the collar. I've reinforced this line with a row of single crochet chain, to stabilize the shoulder line.
The edges of the cardigan lie nice and flat - it's a simple edge - K3, P1, K1, P1 (on wrong side, K1, P1, K1, P3) and then on with whatever the body is. The 3 stockinette stitches at the edge curl to the wrong side and the 3 stitches of ribbing contain the amount of curl very effectively. You can see the wrong side of this edge on the collar.
I'm contemplating my next project. I have a muslin cut out for this skirt.
The problem is, as designed it's pretty skin tight. I've added 2 cm at CF and another 2 at CB, because I'm contemplating it in a woven suiting instead of a cotton-lycra sateen as Burda intended.
I need another suit...
