Also may be called Harry Potter House Scarf Pattern (1st and 2nd movies).

Pattern does not list yarn requirements as the original knitter bought cones rather than skeins, so their guess was three skeins dark and two light. Look at similar scarf patterns to get a good idea of how much yarn to buy.

Someone could also knit the pattern and report how much yarn they used: hint hint.

The designer does not list an actual name; name given is their username.
