As peck said, I actually have a cutting of my families tartan that my grandmother got on a trip to Scotland. It is a woolish type feel to it. I would ask her if she wanted a "real" tartan or just a plaid fabric. if a real one you might want to let her know that most are in a wool. you might contact some Scottish fabric shops and see if they have a tartan fabric that is not in a wool. but that is just my two cents. good luck.
