Reminds me of Agile development, but for camping gear: In the morning, I would cut out an improved model, in the afternoon I would sew it, assemble it and then sleep in it that night. Each morning I would make a note of all the little adjustments to make it a little more comfortable or a little simpler or lighter. Then I would start again, cutting, sewing, sleeping in the hammock. I did this every night and day for two weeks straight.
