Here is the result of the pondering-trying-knitting:

I quite like it !

Yarn : Cachemire de Plassard, 4 1/2 balls (4 balls multi colors dyes, 1 ball beige shade)
Size : 160 cm x 18 cm (but rolling)
Easy-peasy to knit, the stocking stitch is a bit boring, but the striping makes it still fun. And it is sooooft. And Happy !
And now for some Xmas knitting...
Happy knitting to you all!
