Look, I have to disagree here. Most modern bookbinders avoid hidden stitches because they add hours of work for little visual payoff. It's not just about tension, it's about the whole method being way more complex than standard stitching. You rarely see it outside of high-end restoration or specific artistic binding. Calling it just another method really downplays how skilled and uncommon it actually is.

Ever try making it with dried ones? I switched last month and soak them overnight with some baking soda. The texture gets way creamier than canned, but my blender did struggle a little with the thicker mix.
