I've had an interest in weaving, looms, yarns and textiles since I was a small child. I learned to knit, crochet, sew, do needlepoint at my mother's knee. My grandmother was a Saami from northern Norway. I am very interested in studying more about traditional Saami and Finnish style weaving and handicrafts. Paivi Suomi
