Hey Kopio, welcome to the Forum! (I have a sister who lives in Meridian.)
For a good place to start, try this: http://www.ianatkinson.net/leather/toolset.htm
Ian Atkinson lives in the UK, and he has an excellent set of videos about how to construct basic leather articles, tools and their use, and so on.
The webpage I reference there might be just the thing you are looking for. And you should definitely look through his videos!
