How to print and fold
No special supplies — just your printer and about two minutes.
- Customize your cardAdd your photo or artwork and type your message in the Foldy Cards editor. It's free and there's no account to create.
- Download the PDFDownload the ready-to-print PDF to your phone or computer. You can email it to yourself and print from anywhere.
- Print on letter paperPrint the single page on standard 8.5 x 11 in letter paper. Regular printer paper works; slightly heavier paper makes a sturdier card.
