Control a Deep Corner

Tall boxes create thick end folds.

The task

Tall boxes create thick end folds. This is a practice exercise for an ordinary home gift, not a claim about a perfect finish.

Try it with the material in hand

On a taller box, press the side triangles outward before bringing the bottom flap up. Flatten each layer separately so the paper does not collect as a single knot at the corner. Use a small test sheet first. Keep the box and paper available while you check the relation, because a drawing or calculation cannot reveal every crease.

A concrete example

An invented candle box is twice as tall as the book box you wrapped earlier. Reusing the book-box end fold leaves doubled paper at the lower corners; separate creases make the end flatter. The useful detail is what changes your next cut or fold, not whether the package looks like a shop display.

Where this method stops

Do not cut a notch into the paper near the box corner unless you know exactly how the remaining edge will close. A small cut can run farther under tension. When the real material disagrees with a neat rule, preserve that observation and adjust the plan.

Second pass

After the first end is dry-folded, turn the box over and look at the top face. If the corner pulls the face diagonally, release the fold and reduce the uneven tension. Keep the first result long enough to compare one changed choice.

Field note for next time

Mark which layer made the bulge. On the second end, change only that layer’s crease position; a one-variable change makes the comparison useful.
