Creative Converting (brand)

Its fill-in invitations come with envelopes and match its party tableware lines, which makes coordinating a theme easy.

Not for: Hosts who want custom-printed names and details, or formal events like weddings.

Gartner Studios (brand)

I’d choose its printable invitations for easy personalization and designs that suit a range of party themes.

Not for: Anyone wanting fully custom illustrations or professionally managed printing.

Fill-in vs. custom printed. Fill-in cards need handwriting for each guest. Custom-printed invitations carry the details but need proofing and lead time. This choice decides both effort and turnaround time.
Envelopes included. Confirm matching envelopes are in the pack and sized to the card. Many listings ship cards only, and odd sizes are hard to match.
Writable surface. The fill-in area should be matte. Glossy or foil areas need a paint pen. Ballpoint and gel ink smear on coated stock.
Mailability. Square, rigid or embellished invitations may need extra postage. Non-standard shapes and thick add-ons cost more to mail.
