Pull-tab cards that reveal a tiny story

One sliding strip can tell a small story

A pull-tab card hides a moving strip behind a fixed surface. The strip can reveal an image, move a character, or change an expression. Its success depends on the relationship between the visible window and the travel distance, not the complexity of the artwork around it.

Guide a strip behind a test window

Cut a generous test window in scrap card and slide a strip behind it. Add paper guides that keep the strip aligned without gripping it tightly. Mark the starting and ending positions, then add stops so the strip cannot be pulled free.

Separate strip travel distance from the other decisions so that a later revision has an identifiable cause. Create a plain reference version before adding expressive variation. Preserve that reference while revising, because memory is poor at comparing subtle differences across separate sessions. Compare the versions in the same viewing conditions. A useful acceptance check is whether the story changes cleanly while the tab stays guided and secure. Judge that at the intended viewing size or working distance, where tiny construction mistakes and exaggerated effects can have very different consequences.

Find tight guides and unwanted fragments

If the strip catches, inspect glue squeeze-out, bent edges, and overly tight guides. If an unwanted image appears at rest, adjust the artwork's position on the strip. Test the mechanism before sealing the layers permanently.

Treat a disappointing result as evidence about strip travel distance, rather than immediately adding another effect. Inspect the undecorated structure with the moving or removable parts exposed. Try the intended action gently and watch where force or friction concentrates.

Create a reveal with two stages

Make a two-stage reveal where the first part of the pull changes one detail and the longer pull changes the whole scene. Check whether the participant can discover both stages without needing to tug harder.

Use one small reveal, a two-stage reveal, and a long transition as three deliberately separated trial conditions. Keep the subject, framing, and main materials consistent across those trials. Note what changes first, what remains stable, and where the intended effect becomes excessive. Choose a version for an articulated reason. A useful note names a visible relationship that you could inspect again, rather than simply calling the result better.

Draw the window on the moving strip

With the house tab at rest, trace the window opening onto the hidden strip using a light pencil mark. Repeat at the first and second reveal positions. Those outlines identify the exact artwork areas that will become visible. Keep unrelated marks outside them, and test the sequence before adding the backing. A narrow accidental fragment of the next expression can spoil the intended pause between the two reveals.
