Quick answer: Write on the flat inner panels - left panel for longer messages, right panel above your signature - and never on the moving tab or scene, where folds crack ink and glue points reject it.
Where do you write in a pop up card sounds like a small question until you are holding the pen. Here is the practical answer, with examples you can copy.
The Layout That Works
Open the card flat and you have three writing zones: the left panel (best for the message body), the right panel (greeting line + signature, mimicking letter convention), and the back panel (short P.S. territory). The tab and scene belong to the engineering - writing there means every opening flexes your ink until it cracks.
Special Cases
- Box cards: write on the outer walls' inside faces or the folded base - plenty of room, all static
- Cards with big scenes: keep messages short and let the scene carry the emotion - three lines is correct, not lazy
- Group cards: assign the back panel and right panel to signers; the left stays for the organizer's message
- Very small panels: gel pens 0.5mm or finer; test on the envelope's inside flap first
Ink and Pen Guidance
Fast-drying gel and fineliner inks beat fountain pens on coated cardstock (smudging). Dark card needs white or metallic gel pens - two passes for full opacity. And date every card: on keepsake-grade cards the date becomes the most valuable line in ten years.

Frequently Asked Questions
Can I write on the pop-up scene itself?
On static decorations, yes with a fine pen - a name on a banner is charming. Never on folds, tabs or moving parts; the crease will crack the ink line within a few openings.
Where do multiple people sign a pop-up card?
Panels first, back second, and around the scene's edges third. For offices and classes, the giant-format cards exist precisely because thirty signatures need real estate - see our giant card guide.
How much should a good pop up card cost?
Mass-market laser-cut designs run $6-12; designer hand-assembled pieces $12-25. Scene count and hand assembly drive the price - not the words '3D' on the box.
