A shawl pin is used to secure a shawl by overlapping the fabric and inserting the pin through it.
The provided YouTube video "Morehouse Farm: How to Use a Shawl Pin" demonstrates the method:
- Overlap the fabric of the shawl.
- Insert the shawl pin through the overlapped fabric.
- Exit towards the end of the shaft of the pin.
- Ensure the pin catches a substantial amount of fabric to prevent pulling and secure the shawl. When it is closed, a nice big chunk of fabric is caught, so it doesn't pull.
