Some explanation is in order I suppose...

Take a swiss map, remove text...
For each area
- Create a new transparent layer
- Open the flag, paste it into this layer
- Resize the flag to fit that area
- Go back to the blank map, and magic-select the area (selection is in the shape of a canton)
- Grow the selection by a pixel or two if necessary
- Invert the selection (everything outside the area is selected)
- Go back to the flag layer. Delete the selection (i.e. everything outside the area)
- Layer now contains an oddly-shaped flag, and everything else is transparent.
Repeat as necessary
Merge all the flag-layers into one, for convenience
Select-by-colour the borders, blacken them, fuzz them, colour-to-alpha, and make that a semitransparent layer representing "borders"
Select the not-needed regions, whiten them, and make that into a semitransparent layer to neaten the edges
Export as PNG, wait for comments, redo bits according to readers' comments and preference...

Light

There's also a version with a semi-white layer over the flags to lighten the image a bit and make the borders more distinct
