Since I have come back I have seen this being asked lots online, due to the new quest for crafting, that already starts at lvl 3
Before you start trying to craft what the quest wants you to make you will have to find your own racial style material in order to be able to do it.
The List:
Altmer (High Elf) = Adamantite
Argonian = Flint
Bosmer (Wood Elves) = Bone
Breton = Molybdenum
Dunmer (Dark Elf) = Obsidian
Khajiit = Moonstone
Imperial = Nickel
Nord = Corundum
Orc = Manganese
Redguard = Starmetal
you will need to have one to be able to craft one thing, and most of the crafting wits will take 5-9 of them
Where to find them:
You can pretty much find it in everything, from dressers, drawers, urns, crates and such.
You can also start deconstructing the armor and weapons you dont need, that way you will get them as well frequently. Instead of always selling them, its a fast way to level woodworking, blacksmithing and clothing as well.
Last tip
There will never be a reason to spend gold on getting them, its so easy and just after a weeks playing u will drown in them, even start destroying them
