Choosing canvas for painting: The canvas is usually light-colored, not too thick nor too hard to avoid from making the paint peeling and wrinkle cracking. The most suitable canvas is pure white poplin or cotton cloth with fine texture. White silk without pattern is also a good choice. Some of the tangka pieces are very large and can only be sewed together with two pieces of canvas with very fine stitches. The seams between the two pieces of cloth stitched together should not hinder the integrity of the tangka picture.
Fixed the canvas: Sew it on a thin wooden frame along the four sides of the canvas, tighten the canvas on the fine wooden frame, then firmly attach the thin wooden frame to the large easel with strong rope.
Glue and polish: First, apply a thin layer of glue to the canvas as a "base color" and make it air dried. After that, apply a thin layer of lime paste. When the second layer of paint is dry, spread the canvas over flat areas like planks and tables, rub the canvas repeatedly with a piece of glass, a shell or a boulder until the cloth on the canvas is out of sight.

Draw the outline: When the above parts are all finished, use the gold color to draw the pattern on the clothes, known as “gold painting”. Some of the decorations and other parts of the picture are also lined with colorful lines.
