Omens of War (OoW) Tailoring Guide
Tailoring is a a great Tradeskill to level up if you're looking for a profession that lets you create all different types of bags. There's also a few combines for armor quests/other misc things over the expansions that you might find need you to raise your Tailoring Skill.
Tailoring 1 - 21
Talk to your Guildmaster.
Woven Mandrake 21 - 66
Save all the Woven Mandrake you make because the very next recipe uses it!
Mandrake Root x 2
Picnic Basket 66 - 76
Save all Picnic Baskets that you make, as they are used in Baking to make Misty Thicket Picnics. If you're not leveling Baking as well then sell them to other players that do practice Baking.
Steel Boning
Woven Mandrake
Reinforced Wristbands 76 - 108
Just vendor these after you make them to get some of your money back. North Karana, South Karana, East Karana, West Karana are all good places for you to farm some High Quality Cat Pelts. I'd also recommend checking The Bazaar for them - sometimes you can find them for pretty cheap!
Wristband Pattern
Forest Green Silk Swatch 150 - 190
Forest Green Silk Swatches are one of the best things to make to raise your Tailoring in Classic EQ and they're still worth doing in Kunark but start to decline in Velious and onwards. The Dark Green Dye is hands down the hardest part of this recipe to acquire as it'll have you picking up Evergreen Leaves in Gfay or Butcherblock.
Dark Green Dye
Silk Thread
Acrylia Reinforced Cloak 190 - 242
This is a much more direct but much more costly route for players to level up with. I'd recommend you create all different types of Acrylia Reinforced Armor that way you can recoup some of your losses by selling what you made in The Bazaar.
Paeala Bark Tannin
(Direct Route) 
Arctic Wyvern Hide Belt 190 - 252
The Arctic Wyvern Hides drop from Wyverns on Velious. The best place to farm them is Cobalt Scar which is also where you'll have a chance to farm Othmir Fur which can be used for the Othmir Fur Recipes - another great way to raise tailoring.

Cod Oil
Velium Studs
(Alternate Route) 
Holgresh Fur Cap 190 - 250
Holgresh Fur comes from Holgresh enemies which you'll encounter in Wakening Lands on Velious as well as in the Everfrost LDoNs. I'd recommend checking The Bazaar for what's available - you might get some for rather cheap!

Vial of Distilled Mana
(Direct Route) 
Othmir Fur Cloak 250 - 295
Othmir Fur is one of the best ways to raise your tailoring all the way up to max but it'll require a decent amount of farming to accomplish. You'll need to hunt Othmirs in Cobalt Scar which come in groups and might be tough for someone soloing.

Ice Silk Sleeves 290 - 328
Ice Silk Swatch is made from Ice Burrower Silk which drops from enemies in Western Wastes.
