Hi Rafa, I've been following your work for a couple of years and am continually impressed every time you create something new. With my praises in mind I have a suggestion for you. Your notebooks are so mechanica looking but they are bound with string which lessens the impact. Look for another binding technique even if it is wire. Good luck and keep up the work, you're an inspiration.
is there any chance of you doing a tutorial for these beautiful books? i'd love to try my hand at one, but i can never get the ends of my board looking as good as yours
