Thanks to @timtsuga’s great and detailed layers of map files, I was able to add rivers and streams to a Michigan map wooden jigsaw puzzle I’ve worked on off and on this year! This is just a prototype on draft board, but I’ll do the finished out of maple plywood or maple hardwood. Loved using the Draft Score setting-- worked great for the rivers and streams. And, this is just the Lower Peninsula-- the Upper Peninsula is in the works. Takes a bit to manually adjust the puzzle piece shapes of something like this with such an irregular boundary so that the edge pieces are still of decent dimension. Downside to an accurate border is that I am pretty sure the Old Mission Peninsula will break off right away, and not much I can do about it at this scale (map is 7 inches tall). I’m also a big fan of trains, so I may do another version instead scoring the railroad routes in the state (sadly mostly not passenger RR) instead of rivers & streams.
