I was born in 1969, and I spent most of my life doing physics and mathematics. The bookfolding began in a second hand charity bookstore, where I volunteer since 2013. All books are donated. We receive so many books that we can't possibly sell them all. But precisely the ones we discard tend to appeal to me the most; the old, imperfect ones that make you wonder who read and treasured them for so long. I wanted to rescue those, and give them a new life.
So I googled 'second hand book art', found some examples, and got to work. Starting by imitating Isaac Salazar, I got more and more ideas. Meanwhile, I developed my own style: I thoroughly determine beforehand how to reach my result while doing the least damage to the book, I like to use geometry and symmetry (my mathematics background comes in useful here), and self-reference, which means that I use a book to express an idea about a book. I started out making only sharp folds, now I am experimenting more with bending or curving the pages.
Also, I make collages from discarded magazines, which often contain beautiful photo's. I cut intuitive shapes from colors or patterns that appeal to me, and combine them into surreal landscapes.
