Meeting on a Vertical Warp Thread:
When the areas meet vertically on a single warp thread, you can either:
- Separate the Areas: This involves creating a clear demarcation between the two colors.This is the kilim technique.

- Join the Areas: This blends the colors together for a more cohesive look.
The choice between Kilim and perfilage will depend on whether
you want a clear demarcation or a more blended effect:
- Kilim Slit: For a straight and basic look.
- Perfilage: For a softer look.
