In fantasy maps coastlines are sometimes portrayed using a combination of two parallel lines and wave shapes on the seaside. I wish to replicate this behaviour for a custom coastline (a path) in Inkscape.
My initial attempt in emulating this was to trace a repeated double line & wave pattern along a path. Doing so however rotates the pattern along the path, where I'm looking for the waves to remain horizontal to the page.
How can I best approach this?
