As it stands Horde can't get Bright Yellow Shirt Pattern and I would love someone forever if they could somehow get it to me via the Gadg AH, I'm a poor warlock but I can reimburse them for their troubles.

They're sold by the tailoring supplies vendors in Darkshire, and here's the thottbot item page incase someone wants it :

A bright yellow shirt, imagine the possibilities! <3

there is a reason for that ... better dont trade it in gadg or risk getting banned!

I'll go check Duskwood out for that. If it's there I'll let you know. :P

I bought the pattern, I'll try to get a Horde to msg you so we can work out when to put it in Tanaris.
