Bold Number Birthday Party Theme

Bold Number is a fun, graphic birthday party theme that puts the big number front and center. It works for any age, from a kid's birthday to a milestone celebration, because the number is the star of every design. Because the design is simple and graphic, it photographs beautifully and pairs easily with balloons, streamers and whatever color scheme you already have in mind.

Every piece can be personalized, so the details carry the guest of honor's name, age or the party date and become keepsakes your guests take home.

Bold Number Signs, Cups, Napkins and More

Start with the Bold Number Personalized Birthday Sign for the welcome table or the cake. For drinks, choose Bold Number Birthday Stadium Party Cups, Shatterproof Party Cups or Foam Cups, and add Bold Number Birthday Can Coolers. Bold Number Personalized Birthday Napkins match the table, and Bold Number Birthday Party Favor Treat Bags send guests home with a treat.

How to Plan a Bold Number Party

Set the sign where everyone will take photos, keep cups and can coolers at the drink station, and lay out napkins with the cake. Favor treat bags make an easy finishing touch at each seat or by the door.

Personalizing Your Bold Number Decor

Personal details are what make party decor memorable. Add the name, age or date to the sign and napkins, then match the drink station with one or two cup styles so guests can grab whatever suits their drink. Plan on one or two cups per guest, a can cooler for canned drinks, and napkins for both the food and dessert tables. We send a digital proof before production, so you can check every name and date before anything is made. Browse more kids birthday party supplies or adult birthday party decorations.
