I've noticed that my Not A Gryffindor Scarf on Ravelry is marked "pattern not yet published." There's a reason for that. It's not a very interesting pattern, more of a recipe, or a knitting meditation.
Use yarn appropriate to the needle size. Swatch if you are unsure.
Cast on a number of stitches evenly divisible by three. Ideally, the number is also divisible by two, because that means you just reverse the knitting and go. Unless you choose to do something exotic, like stripes, it's a pretty mindless knit.
Knit 3, purl 3, to end of row.
Knit all knit stitches and purl all purl stitches, to end of row.
Continue to desired length or end of yarn, whichever comes first.
Garnish however you like.
The Not a Gryffindor Scarf notes are as follows:
*Knitpicks Pallette in Yellow and Red (discontinued colors - use Semolina and Pimento for close match)
*Size 4 needles
As above, except change color with russian join every seven rows.
