Yarn: Rowan Handknit Cotton, 43 g for four coasters Hook: 4 mm It's been a cold, cold spring here in Finland, so there's been a lot of drinking tea and trying to stay warm. I even bought some new tea cups, but they were too big for my old coasters. So I made a new set with some never-ending scraps of Rowan Handknit Cotton. Five rounds of double crochet, and one round of single crochet, and you have a coaster!
