For those seeking to edit their saves for the sewing requirement.
Items (max cap is 99):
Bear Fang = Item66
Troll Bone = Item179
Thick Hide = Item181
Variables (max cap is 255):
Sewing = Variable192 (current in-game achievable cap is 45, recommended cap is 29 + 1 in-game craft to reach 30, in case it triggers something in-game)
Recommended Approach: Edit items only and craft the orc armors in-game.
Which one did I do? Neither, I was at 25 Sewing and already had enough material, I was able to level it to 45 in-game without having to edit my main save. But using a backup save, I still went and edited it, increase the materials amounts and tested if it breaks anything in-game, it didn't. Do it at your own risk though. Hope this helps.
