If the damaged/ripped area in the fabric is:

• Away from cell walls, stitched seams, line attachment point.
• Rips not longer than 2 inches (25 mm).

You can use this repair procedure:

• Use patches/tape designed for paragliders (removable by peeling without residue).
  • This is not something you find at a local hardware store.
  • Semi-transparent tape may be preferable for esthetics: Repair kit patches delivered with new wings are likely colored and somewhat opaque, which will show as dark patches through transparency when the wing is overhead.
  • Avoid Spinnaker tape: Semi-opaque, more rigid, permanent bond.
• Wipe the fabric surface on both sides with a barely damp (water only, no cleaner or solvent) cloth to remove dust.
• For both sides of the wing's fabric, starting with the outside:
  • Reason for outside 1^st: Fabric is easier to flatten from less tension/shear than when the cell is turned inside-out.
  • Use a hard book (avoid object with sharp edges/corners) slid inside the cell to provide a flat hard surface to press against.
  • Flatten out (eliminate wrinkles) the fabric to be repaired.
  • Cut a patch with a size that exceeds the damage by at least 1/2 inch (12 mm). Round the corners of the patch, to avoid focused tension and lower the risk of peeling.
  • If this is the 2nd patch, applied to other side: Offset the patch edges from those on the other side, to produce more progressively flexible edges.
  • Apply the patch, avoid trapping air bubbles by rolling the tape onto the fabric. If needed, eliminate air bubbles by applying and maintaining pressure.
• Verify nothing was left inside your wing.
• After each flight, observe your repair to see if patch(es) are starting to peel.
