What is the most efficient way to level up Blacksmithing?

I'd like suggestions as to the most efficient way to level up my Blacksmithing perk tree. By most efficient, I mean the best combination of speed vs expense (e.g. buying advanced items from merchants and deconstructing them may be fast, but not cheap).
In other Elder Scrolls games, there were tried-and-true strategies for leveling up certain skills (cast Detect Life in a crowded town, create 1000 iron daggers, etc). I'm looking for the most efficient way to farm Blacksmithing in particular, but eventually other crafting trees.
Things to consider:
- Is there a town that maybe has a lot of potential iron ore deposit locations nearby its blacksmithing station?
- Can you buy ore/ingots anywhere? If so, does the purchase value offset the scavenging time for ore?
- I remember the game saying you get more "inspiration" (skill XP i guess) from deconstructing items other people have made. Does anyone know what that means exactly? I'd assume it means I get low XP from deconstructing my items, regular XP from store/loot items, and extra XP from items created by other players, but I'm not sure.
It's totally fine to post answers or suggestions that are not specific to the Blacksmithing tree; for instance, if there's a general tip for leveling up crafting perk trees in general, feel free to post as a comment or answer.

Answer 2
Some fighting areas give a lot of drops and then you can get better at fighting and then deconstruct what you get, but stealing, laundering, and fencing items is the best way, but you also need to upgrade the ledgermen skills to do it efficiently and in mass production.
