The geometry of sentiment: engineering a three-dimensional heart

How to Make a Heart Pop-Up Card | Pop-Up Cards · 4:39 · Video: Howcast · Watch at the source

In short: Transform flat cardstock into a moving sculpture. This guide breaks down the precise folding techniques required to create a layered, protruding heart design.

Creating a pop-up effect relies on specific structural folds and tab mechanics. The process begins by preparing a base sheet and a separate heart cutout. By scoring 45-degree V-folds at the bottom of the heart shape and creating partial cuts, you establish the tension needed for the paper to stand upright.

The final assembly uses double-stick tape to secure tabs onto the card's centerline. This allows the hearts to be layered—pushing one back while bringing another forward—to create a sense of depth that moves when the card is opened.
