Step 1.
Take a square sheet, lay it flat on the table, the bottom edge horizontal.
additional information
- if it is two-colored, place the colored side facing the ceiling.
- The corners of the square are: top left, top right, bottom right, and bottom left.
Step 2.
Make a valley fold, vertical, bringing the right edge over to the left edge.
Crease well and then unfold.
Step 3.
Make a valley fold, horizontal, bringing the bottom edge up to the top edge.
Crease well and then unfold.
additional information
- You have just marked the medians of the initial square, they are valley folds.
Step 4.
Turn the folding from right to left.
additional information
- The vertical axis of symmetry and the horizontal axis of symmetry are mountain folds.
- The bottom edge is horizontal.
Step 5.
Form a valley fold, vertical, by bringing the right edge along the vertical symmetry axis from right to left.
Crease well, then unfold.
Step 6.
Form a valley fold, vertical, by bringing the left edge along the vertical symmetry axis from left to right.
Crease well, then unfold.
Step 7.
Turn the fold from right to left.
additional information
- The fold is still a single-layer square with the bottom edge horizontal.
- The vertical symmetry axis and the horizontal symmetry axis are valley folds.
- A vertical mountain fold marks the left quarter of the sheet.
- A vertical mountain fold marks the right quarter of the sheet.
Step 8.
Form a valley fold, vertical, bringing from right to left, the right mountain fold along the vertical axis of symmetry.
Well crease the fold and let it fold.
Step 9.
Form a valley fold, vertical, bringing from left to right, the left mountain fold along the vertical axis of symmetry.
Well crease the fold and let it fold.
additional information
- The folding is a rectangle in a vertical position.
- It consists of 5 single-layer panels, arranged in 3 layers.
- On the ceiling side, a front right panel and a front left panel.
- In the middle, a middle right panel and a middle left panel.
- On the table side, a back panel.
- The back panel and the front panels are of the same width.
- The width of the middle panels corresponds to half the width of the other panels.
Step 10.
Fold the top edge down over the bottom edge using the existing horizontal crease.
additional information
- The top horizontal edge of the fold is now a hinge edge that connects the front flap to the back flap.
Step 11.
On the front flap, half a centimeter below the hinge edge, make a horizontal valley fold, bringing the bottom edge up towards 12 o’clock.
Firmly crease the fold and let it fold.
additional information
- We now have 3 flaps:
- A large rectangular front flap,
- A very narrow middle panel (5 mm),
- A large rectangular back flap.
- The front and back flaps are connected to the central panel by horizontal hinge edges.
Step 12.
Locate the middle of the bottom edge of the front flap.
Keep it attached, the front flap against the central flap.
Then, through the two layers, make a valley fold, connecting the middle of the lower edge of the front flap to the upper right corner of the middle flap.
Sharply crease the fold, then unfold.
Step 13.
Locate the middle of the lower edge of the front flap.
Hold the front flap against the central flap.
Then, through the two layers, make a valley fold, connecting the middle of the lower edge of the front flap to the upper left corner of the middle flap.
Sharply crease the fold, then unfold.
Step 14.
Turn the two previous valley folds into mountain folds,
while at the same time making a swivel fold with the two central vertical folds at the top of the folding.
To do this, hold the center of the model with one finger while unfolding the left vertical crease, gently moving it to the left until it reaches the upper left corner of the fold.
Well crease the fold and let it fold.
Repeat this fold with the right vertical centerline.
additional information
- The left and right rectangles are now tilted relative to each other.
- On the top part of the model, the vertical slit has become a shallow estuary opening from 11 o’clock to 1 o’clock.
- The bottom edge of the front flap is no longer horizontal; it now forms an angle with sides slanting downward.
- Exaggerated, it resembles the angle formed by the hands of a clock at 8:20.
Step 15.
Turn the folding from right to left.
additional information
- The lower part of the fold corresponds to the front flap.
- This front flap slightly overlaps the back flap.
- One could imagine that this flap represents:
- A left traffic lane,
- A raised central pedestrian lane,
- A right traffic lane.
- The changes in thickness correspond to the gutters.
Step 16.
Form an oblique valley fold by bringing the right part of the horizontal top edge (of the front flap) from top to bottom towards the left, along the right gutter.
Crease the fold well, then unfold.
Step 17.
Form an oblique valley fold by bringing the left part of the horizontal top edge (of the front flap) from top to bottom towards the right, along the left gutter.
Crease the fold well, then unfold.
Step 18.
Fold from right to left, the right traffic lane, onto the right half of the raised central pedestrian lane,
Then flatten the triangular pocket that has formed in place of the upper right corner of the front flap.
Step 19.
Fold from left to right, the left traffic lane onto the left half of the raised central pedestrian lane,
Then flatten the triangular pocket that has formed in place of the upper left corner of the front flap.
additional information
- The front flap of the fold looks like a rectangle in a vertical position topped with a trapezoid in a horizontal position.
- The top edge of the front flap corresponds to the small base of the trapezoid.
- The large base of the trapezoid is wider than the width of the rectangle with four layers.
- The upper part of the folding mainly consists of 3 large single-layer rectangular back flaps that overlap.
Step 20.
Form a valley fold, folding from the outside to the inside, the right half of the right back flap over its left half.
Make sure that the small top edge of the folded flap is properly aligned with the back section.
Crease the fold well and let it fold.
additional information
- The upper right back flap is now double-layered.
- The right part of the horizontal trapezoid is no longer visible.
Step 21.
Form a valley fold, folding from the outside to the inside, the left half of the left back flap over its right half.
Make sure that the small top edge of the folded flap is properly aligned with the rear section.
Clearly mark the crease and let it fold.
additional information
- The upper left rear flap is now double thickness.
- The left part of the horizontal trapezoid is no longer visible.
Step 22.
Turn the folding from right to left, then rotate it so that the bottom edge becomes the top edge.
additional information
- There is a right front flap and a left front flap, both are double thickness.
- One single-thickness middle flap.
- A right rear flap and a left rear flap, both single thickness.
- On both the ceiling side and the table side, there is a slit along the vertical symmetry axis.
Step 23.
Locate the point corresponding to the middle of the vertical slit on the front face.
Step 24.
On the upper right front flap, make a diagonal valley fold connecting the middle of the vertical slit and the top right corner of the fold.
Mark the fold well and let it fold.
additional information
- What was formerly the top left corner of the upper right front flap is now on the outside, on the right side of the fold.
Step 25.
On the upper left front flap, make a diagonal valley fold connecting the middle of the vertical slit and the top left corner of the fold.
Mark the fold well and let it fold.
additional information
- What was formerly the top right corner of the upper left front flap is now on the outside, on the left side of the fold.
- The entire structure now resembles a very open collar; these folds will form the shoulders and sleeves of the garment.
Step 26.
Fold back from right to left, and mark on the vertical axis of symmetry a point half a centimeter below the top edge.
Step 27.
On the upper front right flap, make an oblique valley fold connecting the marked point and the top right corner of the fold.
Crease the fold well and leave it folded.
Step 28.
On the upper front left flap, make an oblique valley fold connecting the marked point and the top left corner of the fold.
Crease the fold well and leave it folded.
additional information
- The collar is now formed.
Step 29.
On the lower part of the model, using the existing fold lines, fold the right and left front panels under the model.
additional information
- The lower part of the garment is plain,
- The upper part of the garment is of the other color.
- The collar matches the color of the lower part of the garment.
