I have had some yarn from Ellen, who owns strikkegarnet.dk
It’s Unisono - a German yarn, which change color in the same way as Kauni, but it’s Superwash treated and very soft. However the superwash make it less good for stranded knitting, in particular steeking.
But superwash and small children (or their parents) works fine.
For trying the yarn I knit a childs sweater.
