A prayer flag is made of very few things: a piece of cloth, ink, and a cord or pole to hang it from. Yet the choices within these are important, since the cloth decides how the flag looks, how long it lasts and how it ages, and the ink decides how clear and lasting the print is. Traditional prayer flags are made of cotton, silk is used for more decorative or ceremonial flags, and polyester or other synthetic fabric is common in modern flags because it lasts longer in the weather. The designs are printed in black ink from hand-carved wooden blocks. This guide explains each material, shows how they compare and helps you choose and care for prayer flags with confidence. The material changes how a flag looks and lasts, but its meaning, as a wish for the wellbeing of all beings carried by the wind, stays the same.

The Parts of a Prayer Flag and Their Materials

• The cloth: The flag itself, in the five traditional colors, in cotton, silk, polyester or another synthetic fabric.

• The printing block: A wooden block carved with a mirror image of the mantra or design.

• The ink: Black ink used to print the design on the cloth.

• The cord or pole: The string on which horizontal flags are hung, or the pole that carries a vertical flag.

Fabrics Used for Prayer Flags

Cotton

Cotton is the traditional and most common material for prayer flags. It is light and breathable, so it moves easily in a light wind, and it takes printing well. Cotton fades and frays naturally in the sun and rain, which is part of its meaning as a reminder of impermanence. Cotton flags are also the kind that can be burned respectfully when they are worn out, which is the traditional way of letting them go.

Silk

Silk is sometimes used for finer, more decorative or ceremonial flags. It is smooth and lustrous, and takes color beautifully, but it is more delicate and more costly than cotton, and it is often used for flags that are displayed with extra care.

Polyester and Other Synthetic Fabrics

Polyester and other synthetic fabrics are common in modern prayer flags. They are strong, resist the weather and keep their color longer than cotton, which makes them useful for flags that are hung in exposed places, for long strings, and in harsh climates. Because they do not break down as quickly, they are not burned when they are old, since synthetic cloth gives off harmful fumes when burned, and they are better hung on a tree in a natural setting, buried in a clean place or offered to a monastery.

Cotton, Silk or Synthetic: Which Should You Choose?

If you want the flags to follow the traditional way of fading with the seasons, cotton is the natural choice. If the flags are for a place with strong sun and wind, or if you want them to last for several seasons, a synthetic fabric may serve you better. Both are valid choices, and it helps to think about what happens to the flags at the end.

The Five Colors

The cloth is traditionally in the five colors of the five elements: blue for sky or space, white for air or wind, red for fire, green for water and yellow for earth. They are hung from left to right in this order, and the colors are part of what makes a set of flags complete. In some workshops, the cloth is dyed in the five colors before it is cut and printed.

Wooden Printing Blocks

The designs are printed using woodblocks. For each mantra, prayer or image, a mirror image is carved into a block of wood, so that the print on the cloth reads the right way round. Each block is cut by hand, and a single block can print many flags, which is why this method has lasted for so long. The carving is skilled work, since the letters and the fine lines of the wind horse and the four animals must be clear. Different blocks are used for the different mantras and deities.

Black Ink

The prints on our prayer flags are made with black ink. It is worth understanding what this ink is, since it determines how clear and lasting the print is.

For a fuller guide to the ink, including how it is made and how it is used on the block, see our article What Is Prayer Flag Ink Made Of?

What Is Traditional Black Ink Made Of?

The oldest black inks are made from soot. Fine black soot, called lampblack, is collected from burning oil, resin or wood, and then mixed with a binder, a sticky natural substance such as a plant gum or an animal glue, and water, so that the ink can be spread and will cling to the surface. This kind of ink is known in many parts of Asia, and it gives a deep, matte black. The exact recipe differs from place to place and from maker to maker, so there is no single traditional formula.

What Is Modern Black Ink Made Of?

Modern inks for printing on cloth often use carbon black, a very fine black pigment, together with water or another carrier and a textile binder that helps the ink bond with the fibers of the cloth. Additives improve how smoothly the ink prints, how fast it dries and how well it lasts in the sun and rain. Ready-made textile printing inks are widely used because they are consistent and can be matched to cotton, silk or synthetic cloth.

Which Ink Lasts Longest?

How well the ink lasts depends on more than the black pigment itself. The pigment is made of carbon, which does not fade, but the binder and the cloth decide whether the print holds up in the weather. A binder that suits the fabric helps the ink grip the fibers, while the wrong binder can let the print rub off or wash out. This is why makers test the ink on the cloth before printing. Because flags are meant to fade slowly in the wind, a print that gradually wears is natural, and a print that is clear when new and lasts for a season or more is a sign of good materials.

Cords, Poles and Fittings

Horizontal flags are sewn or tied to a cord, usually of cotton or synthetic string, which is strung between two points. The flags are kept in their order of colors along the cord. Vertical flags are attached along one edge to a pole of wood or bamboo, or to a metal pole, which is planted in the ground. Cotton cord weathers in the same way as cotton flags, while synthetic cord lasts longer, so it is common to match the cord to the cloth.

Caring for Prayer Flags

Hang prayer flags outdoors in an open place and let them fade with the weather. Do not wash them, since they are meant to wear in the wind. Keep them off the ground, and keep the set together in the order of the colors. Old cotton flags can be burned respectfully, while synthetic flags should not be burned, and none should be put in the rubbish. If you are unsure, ask a monastery or your teacher.

How Our Prayer Flags Are Made of These Materials

We sell almost all types and sizes of prayer flags, from very small flags to long and large ones for monasteries and hillsides. They are printed in the traditional way, from hand-carved wooden blocks bearing a mirror image of each mantra or design, onto cotton, silk, polyester or other synthetic fabric, using black ink. Because the work is done by hand, each flag is slightly different, and each product page lists the fabric and the details of that piece.

Our prayer flags are not blessed. We do not sell blessed items, but we can arrange a blessing at the customer's request, on the customer's behalf.
