Fly curtains made of plastic bottle caps

These fly curtain crafts are made of beaded, recycled plastic bottle caps. Each curtain contains roughly 32 plies of 64 plastic bottle caps each, making over 2000 plastic bottle caps per curtain. A fly curtain weighs about 6 kilogram.

Freddy just thinks the cap curtains are beautiful and he is impressed by the properties of the cap curtains: they move, make sound, colors and sparkle, can be viewed from two sides and you can ‘in’ the image through it, as it were. to walk through. He would also like to see that he set a trend and that more people start making cap curtains.



  • 2000 plastic bottle caps
  • 75 m rope
  • board 80x920x12 mm (hxwxd)
  • shelf 80x2200x12 mm (hxwxd)
  • 60 screws 3×16 mm
  • 2 screws 4×30 mm
  • newspaper, colour advertising brochures
  • wallpaper paste
  • drill 3 mm
  • tape
  • knife


Prepare a sturdy board on which to fix the strings of plastic bottle caps: fix 30 screws at a distance of 3 cm. Fix a 4×30 mm screw at each side of the board on which the board can be hung above the doorway.

Glue the newspaper pages with the wallpaper paste to create a surface similar to the size of your doorway, say 90×220 mm. On this created surface, draw the outline of your fly curtain image. Glue coloured paper snippets from the advertising brochure to the surface to indicate where you want which colour. Tape the surface to the board.

Starting from the left or the right, lay the shelf on the surface and lay out one string of plastic bottle caps on the shelf following your outlined image. Drill holes in the selected bottle caps. Remove the sharps with a knife and lace the bottle caps to one string. Fix the string to a screw on the board. Repeat this for the next string and this way make your way over the other side of the surface.

Do final adjustments regarding colours and string lengths. Draw holes in the middle and the side of 30 white plastic bottle caps. Cut out the side-holes with a knife. Fix the bottle caps just above the screws on the board.

Type of rope

I’m using polyethylene, uv-stabilized rope now. I tried hennep rope but this is too prone to tear and wear. For Wave 2 I’ve used nylon fishing line (0.60mm). This is nearly unvisible and holding up fine – capable of stretching nearly 2cm and still returning to its original length, but I’m still curious if this will stand the test of time.

Freddy Vulto (1971) makes curtain caps from used plastic bottle caps that he often picked up along the road. He uses the caps to create images by arranging them by colour.

With his work Freddy wants to inspire and show other perspectives.
