I went for a variation on the Cosy Stripe Blanket from the fabulous Attic 24 blog.
It's a bit mind bending when you see it all together. The colours are very bright. It's such an easy patter pretty much all double crochet, but very cleverly it makes a lace like pattern.
I made it with heavy cotton yarn, and it took a few weeks. I was particularly pleased with the edge- it looks kinda like broderie anglaise I think.
Anyway, she loved it, and she's used it every day since her birthday- or I have, it's so heavy it feels lovely to snuggle under.
Thanks for looking!
