This Northrend Tailoring leveling guide will show you the fastest way how to level your Northrend Tailoring skill up from 1 to 75 as inexpensively as possible.
Often the materials are based on a case that you will gain one skill point for each craft. This won't happen, so you will have to buy a few extra materials while you are leveling your Northrend Tailoring.
If you are still leveling your character, I recommend trying Zygor's 1-60 Leveling Guide to help you get to max level faster. And if you are low on gold, you can also try his Gold Making Guide.
Northrend Tailoring Trainers
You can learn Northrend Tailoring from Charles Worth at Dalaran (Northrend). (this NPC exists in Broken Isle Dalaran too, but he won't teach you Northrend Tailoring)
If you are leveling in Borean Tundra or Howling Fjord, then these trainers might be closer to you:
Raenah in Borean Tundra at Warsong Hold. She's on the 2nd floor of Warsong Hold, standing across from the bottom of the elevator. If you're coming off the elevator, she'll be directly in front of you and to the left. If you're coming with the zeppelin, she will be below you. (Coordinates: 41, 53)
Darin Goodstitch in Borean Tundra at Valiance Keep. If you stand in front of the keep, he is outside to the left side. (Coordinates: 57.4, 72.2)- Alexandra McQueen in Howling Fjord at Vengeance Landing. She is inside the inn. (Coordinates: 79.4, 30.6)
- Benjamin Clegg in Howling Fjord at Valgarde. He's upstairs in the inn. (Coordinates: 58.6, 62.6)
Bandage recipes
The recipes used in this guide are not taught by the tailoring trainers, you have to find a different trainer who will teach you the bandage recipes.
Find Olisarra the Kind and learn 
Frostweave Bandage. (she is in the house to the left from the tailoring trainer)
If you are leveling in Borean Tundra or Howling Fjord, then these trainers might be closer to you:
- Nurse Applewood in Borean Tundra at Warsong Hold. She is on the same floor where the Tailoring trainer is, just go around the ramp (not up the ramp to the zeppelin). (Coordinates: 41.6, 54.4)
- Brynna Wilson in Borean Tundra at Valiance Keep. She is at the northern part of Valiance Keep, standing near a well. (Coordinates: 57.8, 66.2)
- Sally Tompkins in Howling Fjord at Vengeance Landing. She is on the 2nd floor in the building behind the bat handler. The stairs leading up are on the right side of the room as you enter the building. (Coordinates: 79.4, 29.4)
- Anchorite Yazmina in Howling Fjord at Valgarde. She walks around the campfire in Valgarde. (Coordinates: 59.8, 62.2)
