Preparation + 13 numbered steps

Materials

6-inch square · 6 × 6 inches

One 6 × 6-inch square (15.24 × 15.24 cm) of thin origami paper. A yellow front and green reverse work well; plain paper is fine too. Ruler and pencil for shaping marks; optional pen for kernel lines. No scissors or glue.

    PREPARATION · Origami Club sweet corn · original measured adaptation

    Prepare the diamond

    Place the square with one point up and the intended cob color facing you. The reverse will become the two husks.

    Layers: One flat uncut square.

    Check: The top and bottom points line up vertically.

  2. END STATEOriginal left: blue · right: goldCrease the center

    STEP 1 · Origami Club sweet corn · original measured adaptation

    Crease the center

    Bring the right point over to the left point and press the vertical diagonal.

    Layers: Fold the whole right half.

    Check: The side points coincide.

  3. END STATEOriginal left: blue · right: goldOpen the diamond

    STEP 2 · Origami Club sweet corn · original measured adaptation

    Open the diamond

    Return the right half fully to the table.

    Layers: Open the same half.

    Check: A straight vertical center crease remains.

    STEP 3 · Origami Club sweet corn · original measured adaptation

    Fold the right lower edge in

    Bring the lower right sloping edge onto the center crease. Keep the bottom point fixed.

    Layers: Move the complete right corner flap.

    Check: Its old lower edge rests on the center line.

  5. END STATEOriginal left: blue · right: goldFold the left lower edge in

    STEP 4 · Origami Club sweet corn · original measured adaptation

    Fold the left lower edge in

    Match the lower left sloping edge to the same center crease.

    Layers: Move the left corner flap; leave the right flap flat.

    Check: The two front flaps meet along the center and have level upper edges.

  6. END STATEOriginal left: blue · right: goldPeel the right husk outward

    STEP 5 · Origami Club sweet corn · original measured adaptation

    Peel the right husk outward

    On the center seam, mark a point 2.49 inches below the meeting of the two upper flap edges. Fold the right front flap outward and down on the 45-degree line joining this mark to the outer right shoulder.

    Layers: Move only the right front kite flap, leaving the cob backing still.

    Check: The released corner reaches the lower end of a short vertical edge on the right.

  7. END STATEOriginal left: blue · right: goldPeel the left husk outward

    STEP 6 · Origami Club sweet corn · original measured adaptation

    Peel the left husk outward

    Repeat from the same center mark to the outer left shoulder.

    Layers: Move only the left front kite flap.

    Check: A plain diamond-shaped cob is visible above the two lowered flaps.

  8. END STATEOriginal left: blue · right: goldTurn the right husk tip up

    STEP 7 · Origami Club sweet corn · original measured adaptation

    Turn the right husk tip up

    Find the midpoint of the short outer right vertical edge. Crease from that midpoint to the lower point of the plain central diamond, and bring the lower right flap corner up and inward.

    Layers: Fold only the peeled right flap. Do not carry the plain cob behind it.

    Check: A small reverse-colored triangular tip rises beside the cob.

  9. END STATEOriginal left: blue · right: goldTurn the left husk tip up

    STEP 8 · Origami Club sweet corn · original measured adaptation

    Turn the left husk tip up

    Make the matching fold through the midpoint of the short left vertical edge and the lower point of the plain central diamond.

    Layers: Move only the peeled left flap.

    Check: Both husk tips frame the lower part of the cob.

  10. END STATEOriginal left: blue · right: goldNarrow the right side behind

    STEP 9 · Origami Club sweet corn · original measured adaptation

    Narrow the right side behind

    On the upper right cob edge, measure 1.73 inches down from the top point. On the outer lower right sloping edge, measure 4.28 inches up from the bottom point. Fold the whole side backward on the line joining those marks.

    Layers: Carry every layer beyond the line, including the little husk tip, to the back.

    Check: The right cob edge is tall and almost vertical; a slim husk remains visible below.

  11. END STATEOriginal left: blue · right: goldNarrow the left side behind

    STEP 10 · Origami Club sweet corn · original measured adaptation

    Narrow the left side behind

    Mark the same distances on the left edges and fold the complete left side behind.

    Layers: Carry the full left packet, including its returned husk tip.

    Check: The two tall cob edges and tapered husks match.

  12. END STATEOriginal left: blue · right: goldFlatten the bottom point

    STEP 11 · Origami Club sweet corn · original measured adaptation

    Flatten the bottom point

    Measure 0.75 inches up the center seam from the bottom tip. Fold that tip backward on a horizontal line through the mark.

    Layers: Move all layers in the little bottom triangle.

    Check: The long husks now end in a short flat base.

  13. END STATEOriginal left: blue · right: goldSoften the cob top

    STEP 12 · Origami Club sweet corn · original measured adaptation

    Soften the cob top

    Mark a point 0.35 inches down the center crease from the top tip. Fold the small top triangle behind on a horizontal line through that mark.

    Layers: Move the top corner to the back, keeping the front cob plain.

    Check: A short flat top joins two sloping shoulders above the long cob.

  14. END STATEOriginal left: blue · right: goldAdd optional kernel lines

    STEP 13 · Origami Club sweet corn · original measured adaptation

    Add optional kernel lines

    Leave the model plain, or draw a few vertical lines and short cross-lines inside the exposed cob. Keep the two husks free of the grid. Press the completed corn flat for display.

    Layers: No paper moves in this step. The dark grid shown is optional pen ink.

    Check: The tall cob, two folded husks and flat base are complete.

The source diagram credits Fumiaki Shingu. Design authorship and design-reuse permission have not been independently established; this is not labeled traditional or public domain. Source drawings, animation and wording are not reproduced. These English instructions, geometry, diagrams and optional kernel grid are original.

Adaptation: Follows the eight-panel flat corn sequence, splitting paired folds into separate actions. The source has no numerical shaping landmarks: this version fixes the peeled-flap hinges at 45 degrees, the return hinges through the outer-edge midpoints, and measured backward side/tip folds on a 6-inch square. The cob and two attached husks remain one uncut sheet. The final optional grid is pen decoration, not folded kernels. This is a flat display, not a rounded cob or a separate leaf assembly.
