It took about eight hours before I had the flash. I have a whole lot of scraps of Cascade Eco, it being the one yarn I would knit with for the rest of my life, you know, if I was made to choose and malabrigo Twist didn't exists.
I have two skeins of brown in the stash and one of lime green and a whole lot of scraps. It's not worsted weight so the squares are turning out larger but that will mean less sewing in the end. I cast on 30 stitches on size 6 needle and I'm slipping the first stitch of each row.
The colors aren't a match the original but that is just right for a Weasley blanket. It's more real this way.
