Here is a handy crafting simulator. It only covers Smithing, Clothing, and Woodworking, which are all similar in their mechanics.

Say you are thinking of buying a new weapon, because you want to start training on two-handed as you get close to level 15 (when weapon swap is enabled). You go to this site and find that a Fine level 14 Battle Axe of Training requires:
- 11 Iron Ingots
- 1-5 Honing Stones (depending on how much risk you want to take)
- 1 Flint (for Argonian style)
- 1 Carnelian
That's handy if you want to build it yourself, or get the materials for another to do so.
As you can see, if you want to share the exact item with another player (say in these forums), you can link to a very specific item, including specific craft station sets.
