I bought a vector EPS image. I want to use my Brother Scan-n-Cut to draw it; this machine takes an SVG and draws a stroke along every path. When I imported the file into inkscape, it turned into a set of paths that are filled to make those lines.
Because of how the Brother Scan-n-Cut works, I want a path that looks, when stroked only, like the filled version above.
How can I make paths that lie along the lines that appear when the existing paths are filled?
