Quick answer: Store keepsake pop up cards closed and flat, in acid-free archival boxes, with acid-free tissue between delicate layers. Keep them away from sunlight, humidity and attics - a closet shelf beats a basement box every time.
how to store keepsake cards is one of those questions that seems simple until you try to answer it. Here is the clear version, with the terminology, mechanics and etiquette explained.
The Archival Method
- Close each card so the mechanism rests naturally
- Wrap delicate scenes in acid-free tissue (regular tissue yellows)
- Layer flat in an acid-free archival box - don't stack heavy items on top
- Store in a dark, dry closet; skip attics, garages and basements
- Open and air them once a year - check for pests and humidity
What Destroys Cards
- UV light - fades inks within months on a sunny sill
- Humidity cycles - warp paper and loosen glue
- PVC plastic sleeves - emit acids over time; use polyester (Mylar) if sleeving
- Attics: heat and pests; basements: damp
Alternative: Digitize Then Display
Photograph the open card in daylight, then rotate a few on display (display ideas) and archive the rest. Wedding and baby cards deserve the full archival treatment - see wedding keepsake designs.
