Vent your kite with Christiaan

Dutch kite flyer Christiaan van Oosterhoudt documented how he turned a standard quad-line kite into a vented quad-line kite. This restored making-of shows the process in 16 steps: preparing templates, cutting, fitting the mesh, gluing, sewing, and finishing the sail.

We translated the page into French and English, added captions, and sometimes reorganized the order for clarity. See also his full making-of of a Revolution kite.

This modification is difficult to reverse. Vent dimensions and placement must suit the model, intended wind range, and sail structure.

Before cutting an existing sail, review the methods for preparing patterns and panels and for sewing and finishing the sail.

The steps may look simple, but they require precision: laying the sail flat, making clean cuts, and so on.

Preparing templates for the vents
Placing the templates on mesh and cutting with a cutter
Collecting the cut pieces

The sail not yet vented
Flattening the sail on the plan
Using weights to match the plan and stabilize the sail
Checking the mesh position on the sail against the plan
Running a thin bead of glue around the future vent edges
Placing the mesh on fresh glue
Letting the glue dry
Sewing the mesh edges
Flipping the sail and trimming with small scissors

Final result: the vented kite

Christiaan’s making-of documents one complete approach, but venting depends on the kite model, frame, and intended wind range. These discussions show other choices, questions, and uncertainties; they complement the photos without forming one universal method.
