Buying Guide
- Quantity and guest list: Choose a set that matches your guest count or offers flexible bulk options to accommodate changes.
- Card stock and durability: Heavier stock (around 250-350 gsm) resists bending and supports clean handwriting, especially for mailers or hand-delivery invites.
- Design and theme: Pick a design that aligns with your party’s color palette and overall theme—bright, playful visuals for younger kids or watercolor, softer tones for a more refined look.
- Fill-in vs. pre-printed: Fill-in cards offer personalization, but pre-printed lines help guests fill in details quickly. Consider envelopes that seal easily and protect contents during mailing.
- Envelopes and sealing: A set that includes envelopes saves time, while self-adhesive or easy-seal options minimize prep work for busy hosts.
- Environmental considerations: Look for recycled or responsibly sourced paper options if eco-friendliness matters to your household.
- Printing quality: For dual-sided invitations, ensure the design prints clearly on both sides without bleed or smudging.
- Personalization and messaging: If you want to include RSVPs or a link for event updates, choose a design with ample space on the back or a printable version for digital sharing.
