Do one daily and post to your journal :)

Some examples:
Past self / present self / future self
Current situation / Obstacle / Advice
What brings you together / What pulls you apart / What needs your attention
You / The other person / The relationship
Strengths / Weaknesses / Advice
You / Your current path / Your potential
Physical body / emotional body / spiritual body
Where I'm a little bit square / where I'm a little bit dense / where I'm perfectly delicious (the brownie spread *g*)

A helpful post on 3 card spreads. If you've Never tried tarot before and don't own a deck, there are many online generators where you can pick random cards. I've used The Light Seer's official page before; there's a Pick A Card button once you scroll down, and you get the guidebook entry for that card as well.
(hah I just clicked it and got Three of Cups, so friendship, community, and celebration!)
