I have found a nice little yarn shop in Gamla stan in Stockholm called Anntorps väv. I went there to buy the yarn Kalinka, produced by Karin Öberg, in the colour english red. And I mentioned for the shop owner that I needed a very thin yarn to crochet earrings, she went immediately to her store stock down stairs in the cellar and came up with a supernice red yarn for weaving. And for free I got a small skein. The yarn was perfect for dangling red earrings!
