Where can I buy a House scarf that actually has the correct colours?

Would it be impossible to *colour* the string to be silver, ゴールド または bronze? No, it would not. Especially with the prices they slap for the products already as it is! Of course, another thing is how comfortable those stripes would feel to wear if they'd been dipped in metal...I don't know.

Anyway, I have a "Ravenclaw" scarf which stripes are dark GREY. It's like they were *trying* to mess it up. I mean, since when was grey anything close to bronze? Most Slytherin and Gryffendor scarves are at least trying to get close without being the correct colour.

So, does anyone know anywhere to buy correctly coloured house scarves, または at least a Ravenclaw scarf which is dark blue with stripes that resemble bronze?
