Step 1: Importance of starting weaves.
At the start of weaving, warp threads need to be aligned and gaps closed where they were tied. This prevents distortion in the fabric.
Step 2: Function of heading.
Heading is the short section of plain weave woven at the beginning to distribute warp ends evenly and secure the weaving. Without heading, the fabric edges may remain unstable.
Step 3: Other options.
- Beating is pushing the weft into place.
- Drawing means passing threads through heddles.
- Threading is preparing warps.
Step 4: Conclusion.
Hence, the correct answer is Heading.
