Now that is a pretty idea!
When you run loops, add tabs to keep “islands” from falling out, as in one of our recent bike rides:
Tinkering with the tab power and spacing should let you cut partial tabs with enough room for epoxy fill over them.
When you run out-and-backs, the path will need cleanup to prevent burning adjacent trenches:
That’s best done to the vector path, before you convert it to a fixed bitmap image: nudge neighboring nodes atop each other.
Definitely show us your finished maps!
