Might want to check out the wiki. It explains the basics about crafting and many other things.
Basically, you could get some leves from your city, and sometimes, you would need to talk to specific NPCs to get the materials needed for that particular leve. If not, then you are already given the materials to start.
Then you'll need to select crafting in the main menu, and click on the button to craft the requested items when the crafting window pops up.
That's pretty much how you start crafting, everything else is just about knowing how to read the colors of the orb and know the different commands during the craft.
Accumulating bad luck... One day at a time
