How to plan 18th birthday party decorations

Pick two or three colours first and buy everything to match, from the table covers to the balloons. Black and gold suits 18th birthday decorations for a boy or a mixed crowd, while rose gold and white or pink feels softer. Put a centrepiece weight on each table with a small balloon bunch tied to it, and keep the bigger foil balloons for the entry or the cake table. A guest book or signature block gives friends something to do at the party and leaves the birthday person with a keepsake. For 18th birthday tableware, add plates, cups and napkins in your colour, such as our gold partyware.
