Chrissy's party planner Lisa Vorce sticks to three simple rules when setting the scene.

• Design: Mix and match textures and colors to create a look that ties all your pieces together.

• Soul: Add personal touches—if your secret sangria recipe is what's going in that extra glass, that totally counts.
