How many of you have air cleaners in your sewing areas?
When I use to sew "production style" I always set a portable air cleaner as close as I could to where I was sewing.
At the end of a session of sewing, the filter would be covered with a fine gray dust, which I would vacuum off.
I feel this kept that much dust from going into my lungs.
I have asthma now, but it could have been so much worse.
Even when I sewed on white, the dust was still gray. The darker the fabric, the darker the dust.
Take care of your health dear friends.
