One technique I love is die cutting or cutting with my Cricut or Silhouette (yes I'm spoiled and have both). And the icing on the cake is having coordinating stamps!! LOVE that about CTMH and Cricut.
Another fav technique is adding glitter/sparkle/shimmer to an image. That's the frou frou in me.
One more technique (if you want to call it that) I almost always do when creating cards is decorate the inside of the card. It doesn't feel complete unless I do - I love coming up with new ideas to match the inside to the front.
For this card I used Mojo Monday's Sketch 363.
