I like to dress my builders in special clothes (all one color, like all brown) so I can tell who is who, and if I see one of them doing nothing, I can just drag them back to work. You do need the sewing hut to do this though. You said that you built all of your buildings already, so you should have it.
I dress all my people in special clothes assigned to their task. It is easier to keep them to work. Doctors are white, researchers are blue, farmers are green, builders are brown. Esteemed Elders have their own clothes too.
