I'm a slow to be reformed smoker.
I have asked people who recieve my fabric if they can smell any sort of smoke on it and they all have said no. There is a no smoking policy in the house. I wear a shirt when I am near hubby who smokes ALOT and when I "think" I need one. I also wash my hands before I handle any of the fabric, doesn't matter what I've been doing, my hands are always washed before I go into my sewing room.
And yes, I'm one of those that does sniff fabric that comes from others. A few have been smokers and I have not been able to smell anything on the fabric.
