Sorry no one seems to have responded to your post. The forum you posted in is kind of a "let's get acquainted" one, so you might get more replies if you post in the General Stamping forum.
That said, I think it's very sweet for you to make a card for your friend. I am sure she would love to see a greeting in her native tongue.
I would think any type of card maybe with pretty flowers and colors would be appropriate for a Thinking of You sentiment.
