Clearing out cards after a birthday or a holiday can feel harder than it should. A card from that day might still make someone smile when it turns up again. Americans buy about 6.5 billion greeting cards a year, and the vast majority cost between $2 and $5, a price set for something read once. Pop-up cards get a different reaction, because a scene rising off the fold makes the person opening it want to watch the scene rise again. That urge to open a card a second time is how a keepsake starts.
Most Greeting Cards Were Made for One Reading
A standard card does its whole job in a few seconds. Someone opens it, reads the message and props it on a shelf until the decorations come down. After that, it goes out with the envelope it arrived in, usually the same week.
A pop-up card saves its best part for the moment someone opens the cover. Cards from Designer Pop fall into four kinds, 3D, interactive, light-up and music, and each kind opens a different way. On a light-up card, the glow starts as the cover lifts, while a music card plays its song as the scene stands up. Because something happens in their hands, the person who opens one of these cards may call someone over to see it.
Pop-Up Cards Come From Five Centuries of Paper Engineering
Anyone who has watched a child pull the tab in a pop-up book has seen paper engineering at work. In 2010, the Smithsonian Institution Libraries opened an exhibition on the craft at the National Museum of American History. Called “Paper Engineering: Fold, Pull, Pop and Turn,” it showed more than 50 works. Its books ran from the 15th century to modern times. Among them were peep shows, accordion books, pop-up books and volvelles, which are paper wheel charts that turn on a page.
Before any of these books entertained anyone, they did serious work. They helped explain science and medicine, and the Smithsonian notes they also gave teachers new ways to present arithmetic and reading. A 1662 book by René Descartes used stacked paper layers to show the organs of the body. Pop-up books arrived as toys in the 18th century, and later paper engineers such as Lothar Meggendorfer and Ernest Nister built theirs by hand.
Modern pop-up cards come out of the same craft as those books. A paper engineer plans each fold, tab and cut so the scene stands up when the card opens. Those same cuts let the card lie flat again when it closes. Opening a pop-up card puts a small piece of paper engineering in someone’s hands, which is part of why throwing it out feels wrong.
Card Buyers Are Paying for Cards Built as Objects
Card shoppers are already spending more on cards that do something when someone opens them. According to the Greeting Card Association, cards with intricate designs, sound chips or LED lights sit at the top of the price scale. Handmade cards sit there too, and together they make up the fastest growing part of the market. Prices run from 50 cents to more than $10, and cards near the top of that range usually have extra parts built in.
A higher price changes how someone treats a card once it arrives. Shoppers weigh art and design right alongside the message, according to the association, so the look of a card is part of why someone chose it. When a card cost more than usual and someone took time to pick it out, tossing it a week later feels wasteful. It goes in a drawer, a memory box or the back of a bookshelf.
Why Milestone Occasions Fill the Keepsake Box
When someone moves, marries or has a baby, cards start piling up on the counter. The Greeting Card Association says buying a house, getting married and having children drive card buying. Millennials entering those stages buy cards at a higher rate than Gen Xers did. They pick higher priced cards, too. A card from one of those weeks records who showed up and what they chose to write.
Wedding cards usually come straight from people who were in the room. In fact, family and friends hand deliver two-thirds of them, the association reports. Keeping a wedding card afterward works like keeping sentimental gifts, since the object stands in for the person and the day. When that card also unfolds into a scene, it starts to look like something to store with the guest book.
Birthdays join the keepsake pile at the round numbers. Birthday cards make up more than half of all cards sold. At a 30th or a 50th, more of those cards end up saved. New babies, graduations and retirements follow the same pattern, since each of those days marks a change that will not repeat.
Pop-Up Cards Work Again Every Time Someone Opens Them
Five years after an anniversary, someone digs through a desk drawer for tape (it is never where it should be). Instead, they find the card from that night and open it. Its paper scene rises off the fold at the same speed and in the same order as the first time. For a few seconds, the years in between feel shorter, and if the card has lights or music, those come on too.
Some people take these cards out to show a grandchild or a new partner. Over the years, the card picks up a second set of memories that way. Because pop-up cards fold flat and rise again by design, they can go back in the drawer after each opening. Storing them flat, away from anything heavy, keeps boxes and books from crushing the folds between visits.
Questions About Keepsake Cards
Are pop-up cards worth keeping after the occasion?
Yes, when the card marks a once-in-a-lifetime day. A wedding, a new baby and a milestone birthday all fit. One quick test is to imagine finding the card while packing for a move. If that thought brings the day back, the card has earned a place in the keepsake box.
What should you write in a card someone might keep?
A keepsake card works best with the date and the reason written inside. Ten years from now, the reader may not remember which birthday it was. A few questions can fill in the rest of the message: What is going on in their life this year? Where are they living, and who is around them? What would they be glad to remember about this stretch?
What can you do with old greeting cards you don’t want to keep?
Photographing the front and the message saves the memory, and then the paper can go in the recycling bin. Keeping one card per person from each year is another way to shrink a stack without losing anyone. Pop-up cards with lights or music have a small battery inside. That battery needs to go to a battery drop-off before the card goes in the recycling.
Before the Card Goes in the Envelope
A retirement or a 40th anniversary is the kind of occasion where the card may still be around in twenty years. For a card like that, the format can follow where the person keeps things now. Someone with a shelf by the front door has a spot for a 3D scene that stands on its own. A card with lights or music can sit on a desk where coworkers stop to open it.
