Hey, well I found some easy ways to make gold!
Well the first way is from an alliance vendor in Zangramarsh located at Orebor Harborage, his name is Muheru the Weaver. He sells two tailoring patterns that can be bought for 6g each. But I sold them at the auction house for 20g each!
The next way is a vendor in Shadowmoon Valley at the sanctum of the Stars. He also sells two patterns that sell for 6g, but can be auctioned higher. I hope this helps.
