(3) Sawtooth weaving, that is, weaving sawtooth patterns on the side of the grass stalks, such as various rice dumplings, serrated stalks and winged stalks. (4) Warp weave, that is, through the rotation and folding of grass stalks of various colors, patterns are formed, such as small folds. The weaving patterns of straw hats are varied, some on the sides, some in the middle, and some are all woven into patterns. It often uses techniques such as changing patterns, changing colors and leaving blank to weave into a continuous and lace-like artistic effect.
