I have a dog and a cat. They fabric is stored in a pet free room and they are not around the fabric, but, when I am sewing my cat does sit on my shoulders and I might be hairy from either animal. I do not smoke so that wont be a problem. I do lint roller the blocks before bagging them up, but I truly cannot guarantee no cat or dog dander.
I hope that is not a problem for anyone.
I am having a lot of fun just finally sewing again.
