Decorations

• An arch made of alternating blue and white helium-filled balloons tied to a nylon cord can welcome guests to the party. Other appropriate decorations include snowflakes for a winter party and sea shells and blue tinted water for a summer party.
  
  

Tables

• The tables at the party are one of the most prominent locations to showcase the blue and white theme. The tablecloth can be mostly white with blue details such as stripes, if desired. You can pair blue flowers like hydrangeas with a few kinds of white flowers in a centerpiece. For the table settings, many china patterns include blue designs around the edges.
  
  

Food

• Many blue and white foods are fancy enough for a party. Ideas include white cheesecake with blueberries on top, blue corn chips with white bean or sour cream-based dip, blue punch for kids and mixed drinks with blue liqueur for adults.
