Fold an End in Three Moves

Top, sides, then bottom gives the open end structure.

The task

Top, sides, then bottom gives the open end structure. This is a practice exercise for an ordinary home gift, not a claim about a perfect finish.

Try it with the material in hand

At one open end, fold the top flap down first. Push the two side sections inward to create triangular creases, then lift the bottom flap over them. Press each crease gently with a fingertip before taping. Keep the box and paper available while you check the relation, because a drawing or calculation cannot reveal every crease.

A concrete example

A rectangular craft box has enough overhang but looks lumpy when both side wings are folded over the top at once. Making the side triangles first moves their bulk to predictable corners. The useful detail is what changes your next cut or fold, not whether the package looks like a shop display.

Where this method stops

The fold sequence does not fix a flap that cannot reach. If a corner remains exposed after a dry fit, reopen the end and add paper before placing tape. When the real material disagrees with a neat rule, preserve that observation and adjust the plan.

Second pass

Try the second end without watching the first. Compare the triangles: are they similar in depth, and is the bottom flap centred? Correct the fold order rather than trimming randomly. Keep the first result long enough to compare one changed choice.

Field note for next time

Place a small pencil dot at the top centre during practice. It helps you see whether the lower flap rises straight or slides to one side.
