Scharlata, I think this thread quite clearly that people do have a hard time distinguishing Craft and Profession!
For myself, the preferred method is simply to roll up Craft and Profession into a new skill Artisan, so there's no doubt about what it's under. (For reference, use whichever bonus of Int or Wis is higher).
The only wrinkle I add is that I have such a thing as Artisan (merchant), which represents the skill of leveraging goods and services for wealth. That way I can distinguish between the skilled Journeyman (say with Artisan [blacksmith] +7) and his boss (who has Artisan [blacksmith] +8 and Artisan [merchant] +5).
However this has strayed far into House Rules territory, for which I apologise. Officially, as Starglim has pointed out, it's supposed to be clear which is which. It's just in reality that it gets nuanced (and then abused by DMs!).
