I was just reading the clip and rip thread, and it made me remember what a local LQS owner told me.
Her mother owned the store before her, and she thinks her mom's lung cancer was caused by ripping fabric. She herself ripped fabric for years, and always had a cough and congestion. She said one day she noticed that particles of fabric dust was always in the air, and she was always dusting and vacuuming because it stayed dusty. She started cutting the fabric, and her cough went away, and her shop wasn't dusty anymore. Now she thinks her mom's lung cancer was caused by breathing the fabric dust for so many years.
I just thought it was interesting. Not saying it's true!!!
