How to visualize texture along borders of multipart polygon

[المشرف العام]

I came across this map and would like to replicate the textured styling found along the borders. I'm starting with a multipart polygon but my process has perhaps too many steps. I'm using QGIS 2.8.2.

1. Processing algorithm: Convert original polygon to lines
2. Processing algorithm: Fixed distance buffer
3. Clip buffer using the original multipart polygon
4. Style the clipped buffer with Line Pattern Fill, adjusting transparency, line width, etc.

Any ideas on how to achieve this effect in fewer steps? I sense I'm overlooking an option like color burst, but where you can use a line pattern as a fill. Or, perhaps there's a way to do an inverted or negative buffer, which would save me the clipping step.
