For my 2nd Ravenclaw scarf, I decided to do the pattern of the first 3 movies. It’s much easier/less annoying than the other pattern because of less color changes!
Size J hook. Caron Simply Soft Dark Country Blue and Grey Heather. I crocheted in front loops only for a thinner scarf and nice ribbed pattern (FLO also works up more quickly than both loops, and scarves are long!).
sc 12 rows blue
sc 12 rows grey
repeat until desired length–usually length of the wearer (and end with 12 rows of blue so both ends match)
