I have also been inspired by white on white cards that I have seen other cardmakers do. I really like how it keeps it clean & simple, without being too plain and boring!
I partially embossed the card base, then added two embossed lines to make a 'panel' underneath to stamp the sentiment.
Teacup stamp was stamped and clear embossed four times onto various patterned papers (I just made a slit in the rim of the teacup and popped the next cup into it to stack them up). Teacups were then mounted onto an embossed circle.
Sentiment is clear embossed.

Thought the card needed something else, so I added a few flowers to soften the edge of the embossed circle.
