If you're thinking it looks like Kureyon, you're right—Margaret has knit another afghan.
Yarn: Noro Kureyon, 12 balls
Pattern: Domino Blanket by Lucy Neatby
Technique: Put all balls of yarn into a brown paper bag, pull one out at random and knit a mitered square, then return it to the bag; continue until blanket is as big as you'd like, finishing off with a solid-coloured edging. Wow!
