My origami purchases
I've purchased 3 books:
Origami Essence by Roman Diaz, the book which I've seen in pdf for sure, but since I folded several origamis out of that book I understood I should have a real copy. Now I have it! I'm happy! It's a very good book full of excellent models. I fully recommend it.
The second book is very beautiful inside, I bought it mainly for inspiration
Paper Crystals by Dave Mitchell, the book I've searched so intensively in my early origami years. Now I have it.
