When you click on your blacksmithing icon, it should come up with what recipes you know. Click on that recipe and you will see what materials are needed for the item you wish to make. If you have enough items in inventory, go up to the anvil with the blacksmithing window open and click on the item u wish to make and click create. If it is a recipe you haven't learned yet but have in inventory, you can right click on it to learn it. Hope this helps
first you need to be a blacksmith. If you're not one go to a trainer and learn. Your skill has to be high enough to learn the recipe and then you can learn it and make it. Then when you can just go to an anvil go to blacksmithing and click create on the pants.
I don't believe that to be correct
