I did a little shopping at beauty.com and found The Laundress fabric fresh sprays. I love them. I used it on my curtains, furniture, bedspread, (i'm doing my car next).... They smell so good without being overpowering. I got baby and lady. A two ounce spray bottle is only $5 at beauty.com, nice size for giving it a try. I have a good feeling I will order the larger bottles.
I don't find them strong but I don't have fragrance sensitivity like you so it's hard to say. I would describe them as soft, clean and fresh not perfume-y If you were to use them you'd have to spray and walk away. Once it settles, it doesn't leave a heavy scent. But I do notice it when I walk into the room I used them in.
