Two: Take the white string as the warp, knot the white string at one end, fix it on the side of the frame, and wrap the wire around the tooth comb on both sides of the frame. The warp should be tight. Be prepared for the next step. Three: Corresponding to the wooden trough and the line, turning the heald, so that the warp threads are successively staggered to form two upper and lower horizontal planes. Four: The shuttle wrapped around the line passes transversely in the middle of the warp, so that the warp and the weft are intertwined.
