It’s easy to make something that looks like a bucksaw frame, but it’s much more difficult to make one that will cut a lot of wood without coming apart.
It’s easy to make something that looks like a snowshoe, but much more difficult to make one that will allow you to walk on it all day without having to tighten knots or rebuild.
It’s easy to make something that looks like a shelter. It’s much, much more difficult to make a shelter that will perform and keep you warm by taking into account science and the mechanisms of energy transfer.
Details matter, but they are often glossed over. The way they are learned is by making things that fail, learning why they failed, then making them again with that knowledge in hand. The first one of anything that you make is for learning.
It’s one reason why we emphasize the importance of expeditions; in the field the details are everything. Superficial likenesses are nothing.
Through experience and repetition we master and eliminate the learning curve. Almost everyone has heard that old saying that the devil is in the details. I’d add that the delight is also in the details.
