Buying Guide
What design should you choose for a 90th birthday?
Consider the guest of honor’s personality and the party tone. Floral and pastel designs read as warm and celebratory, while black-gold or vintage themes convey timeless elegance. If you want a bold photo prop, a high-contrast or metallic motif can enhance photos.
What size and format work best?
Most invites are 4×6 inches or 4×6 inch cards with envelopes. This size is standard for mailing and display. If you expect a lot of information, choose a double-sided card or a fill-in style that keeps details concise.
Envelope and address considerations
Envelopes simplify distribution and protect the card during mailing. If you plan a formal event, select invitations with matching envelopes and consider pre-printed return addresses or a handwriting-friendly surface.
Materials and writing surface
Coated paper often resists smudging and writes smoothly with most pens. Consider a design that complements your pen choice—dark inks show well on light backgrounds, while metallic inks pair with darker designs for a striking look.
Decoration coordination
Decor sets that match invitations save time and help create a cohesive party aesthetic. If using a kit, verify it includes a coordinated backdrop, balloons, and toppers to avoid mismatches later.
