Step 1.

Make a kite base, lay it flat on the table, with the sharp tip pointed at 12 o'clock.

Step 2.

Form a valley fold, horizontal, by bringing the bottom tip up to the top tip.

Crease firmly, and let it fold.

additional information

  • You get a shape with two flaps, connected by a horizontal hinge edge at the bottom
  • The top flap has 5 sides: bottom horizontal, bottom left, top left, top right, bottom right
  • The bottom flap is a triangle, with its base as the hinge edge

Step 3.

Form a valley fold, by bringing the bottom left edge over to the right, along the vertical symmetry axis. Fold through all layers.

Crease firmly, and let it fold.

Step 4.

Form a valley fold by bringing the bottom right edge from right to left along the vertical symmetry axis. Fold through all layers.

Well crease the fold, and let it fold.

additional information

  • You obtain a shape with a fixed trapezoid part at the bottom, and two flaps connected by a horizontal hinge edge (which is the top side of the trapezoid).
  • The top movable flap has 5 sides: lower horizontal, lower left, upper left, upper right, lower right.
  • The bottom movable flap is a triangle, whose base is the hinge edge.

Step 5.

Form a valley fold by bringing the top movable flap down from top to bottom, using the horizontal axis (the top side of the trapezoid) as support.

Well mark the fold, then lift it vertically (this is the sail of our windsurf board).
