Had the same problem with some outdoor fabric I was working on this past winter. Everyday I came down to work on it I would start sneezing continually, head all stuffed up, just dragged out. Was never so glad when I got the project finished the the leftover fabric stored away. I still have some sneezing when I come down to work with cotton fabrics but I won't give up my hobby. Same goes with the kitty as I also sneeze around her too. Won't give her up either. There are some things we just won't do without due to our love for it.
