Used to be against machine stitching, but this changed my mind.

Bar clamps are your best friend for this! I learned the hard way with a cheap spring clamp that failed. Pushing the router too fast can also pull the piece, so take it slow even with a sharp bit.

What about checking smaller online communities? I've had luck with gear advice from actual hikers in forums (way better than star ratings).

Actually it's not about the "old ways", it's that paper forces you to see the small details. The physical connection to the drawing just works differently for problem solving.

Ah yes, let me just add "find a willing expert to give me free life advice" to my to-do list, right between laundry and staring at the wall.
