Filcolana is a Danish yarn brand, founded more than 40 years ago. Here's what they have to say about their yarns:
"Filcolana sells high quality woollen yarns for hand knitting, crochet and more. We monitor our products from start to finish, which means that we buy up the best wool and then have it spun on the best spinning mills around the world. The yarn is then dyed, wound into balls, given ball bands and shipped to our warehouse in Kjellerup, Denmark. From here it is ready to be shipped out of our retailers: the local yarn stores in Denmark as well as abroad."
