Can I teach a woman how to tie tzitzit?

It appears to me that there is no prohibition to teach a woman to tie tzitzit since it is clearly permitted for a woman to tie. The question of women tying tzitzit is only whether such is l’chathila or bidi’aved – and such a question only falls on the woman herself. Also, it should be borne in mind that the Rama (OH 14:1), who poskins that a woman’s tying is bidi’avad, calls the ruling a “humra”.
