How to create Studs with Smithing
Studs are an extremely easy to make item with Smithing that are used in dozens of different recipes for the Tailoring tradeskill. I'd recommend you raise Smithing to at least 100 to greatly reduce how many failures you get while trying to make this item. Use any of my available Smithing guides for a good route.
Also in order to make Studs you'll first need to craft a File through Smithing, that'll take a few subcombines to make as well - it's very tedious but luckily you only need to make a File once.

Once you have all of the required ingredients, combine them together in a Forge.
