I have outdoor fabric which I find while using it makes me sneeze alot so something within the fabric I'm allergic to. I used mine to make a scrappy cushion cover, a couple pillow covers and a bench cushion. They've been outside during the summer for a number of years and for whatever reason this past summer a squirrel decided to chew thru 3 out of 4 of my pillows on the wicker chairs. I try now working with this fabric any more than I have to due to my reaction to it.
Sitting on it has no effect on me though.
