I have a very sensitive nose. My ex use to try and smoke in my van when I wasn't around. He'd roll down the window, hold the cig out the window and blow the smoke out the window as well. He'd leave the windows down when he got out. I could go out there hours later and still smell it. It took him a while to realize I'd know. I don't let people smoke in my house or my cars. I have cats but they don't come in my sewing room. I leave the door open all of the time but because that and my bedroom has always been off limits they don't go in. They can't come in my bedroom due to cat hairs on my clothes when I go to work. I have met people who are alot more sensitive than I am. If you sell quilts you should let facts about your enviroment be known in advance. Some are also alergic to pet hairs.
