Wool + smoke = death.. Ok, I exaggerate.

Smoke is a very sticky substance, and wool, as we all know, is rather adherent itself.

Bottom line, I can't imagine a way (febreeze, air, other environment, etc) where she will be able to make kilts for her entire pipe band, and not name them the Ash Tray Pipers.

Even if she's not smoking at the time, it's in her lungs, on her clothes, on her hands, etc.. She'll be rubbing it into every yard of fabric that she handles, and febreeze won't be able to touch the damage that she'll do. Chemicals will just mask, so getting that smoke out of the wool is your only bet.

The question is, how do you do that without messing up the kilt? That's beyond my pay grade.
