Weapons crafting in Skyrim

I started playing Skyrim shortly after it was released and I really like this game. My wife also plays it a lot and very often we talk about quests, places, strategies and weapons. Recently I showed her my ebony bow and she was impressed. She is about 10 levels stronger than me but she can't make the bow that good.

That got me thinking how did I make it so good and how to improve that skill even further. At the moment I am testing my process and I'll post here full details how to get really good bow or other weapons. My latest success - killed a giant with a single arrow while sneaking!

Here is a screenshot of my preferred bow.

In next post expect description of reasonably lengthy process that will give you ability to craft powerful weapons.
