ah hail
it been a long time since we talked there a_shikhs.
what i propose is this, as friend i would is
1. come up with 1 beginner book,, one intermediate book that helped you
so she may purchase them at her liesure.
2. come up with an quick outline so she can study on her own, what the cards mean conscisely (this part may help you out as well)
3. give her a quick self study lesson p lan..
to share one thing is i once sat my friend down who wanted to learn and ran through the major arcana with her,, she really wanted to learn.. then after i asked her about it,, she said she didnt' want to learn ,, it was to hard.(i gave her a book and a deck to study the sacred rose tarot and she lost it ).
so i realized i am not a good tarot teacher as i expected her to study on her own.
and i think that is the main part unless you are enthused that you want to teach her the tarot on a weekly basis you have move to get her to study on her own,, yet give her all the resources you perhaps didnt' have like as griz said ,, tell her to come here and start reading threads, the thirteen tarot basics.
