[HPFGU-Movie] Hogwarts scarves

[Odile Falaise]

I have knitted several scarves based on the ones that
the kids wear in the films (there are several websites
out there with the pattern.)

I was wondering: does anyone out there know exactly
what kind of yarn was used (merino? acrylic? ...?),
what particular brand of yarn was used, and what
colors?

I haven't been able to find any of this info online. 
Any suggestions?  Thanks!  ^_^
