I tend to give custom profession names to most of my dwarves to help me tell them apart. My Planter/Butcher is called a Rancher, my Carpenter/Mason/Architect is called an Architect, and my Brewer/Expedition Leader is known as the Brewmaster. On the military side of things, I give my dwarves ranks to tell me what sort of skills they have. Marshals are in charge of the army, Captains and Lieutenants are important fighters, and Privates are nothing more than Troll Fodder; unwanted migrants with no useful military or civilian skills above Novice.
During the second year of my fort, I was informed that one of my Privates had gotten a secretive mood. At first I groaned, expecting him to grab a craftsdwarf's shop and make a useless idol or something. Not so. It turns out he was actually a Novice Weaver, and proceeded to make my a cave spider silk thong. Not very tasteful, but I was plesantly surprised that I now had a Legendary Weaver among my dwarves, who I sent to go collect webs and make some high-quality cloth.
Sometime later I got another migrant wave. Most were Private material, but one among them was a High Master Dyer. That was pretty cool, as he could dye the exceptional cloth my legendary weaver was cranking out. I set a workshop up for him and started shifting some of my farms over to cloth and dye production. Fast forward another year, and my second strange mood also happens to a Private. This time he is a Novice Clothier, and makes a rather valuable rope out of the nice dyed cloth I had sitting around - but that is not the important thing.
I am in the second year of my fort, and I now have a Legendary Weaver, a High Master Dyer, and a Legendary Clothier.
Clothesmaking Industry, anyone?
