I don't exactly know what embelishing is, but I can tell you that it is in fact not enchanting. If you want to enchant a weapon, you don't need a seporate skill for it. Just click on the weapon while it's equiped and the charm window should pop up, allowing you to place charms into the slots (even though they'll come up as X's.)
I have no clue what embellish is, but from the sounds of it, it just increases the value of your weapons...
