What a rude person she is then! Just don't let her get to you, (I know, this is sometimes easier said than done!) Just say to her in front of everyone," Oh right, is that how YOU do it? That seems a good way too, but I've found blah etc works for me!" I've been in this situation before, I know how low it makes you feel, but I adopted the above quote, looked interested in what she said, nodded my head and was SUGARY SWEET to her!

She stopped the put downs after a while! AND I continued doing things the way I was taught! All the best to you
