In this book we have gathered the three great pillars to become a collage artist. Inside you will find three chapters: The A of collage: brief introduction with a review of the precursors of this technique and their different styles; The B of collage: explanation of the necessary tools to create this wonderful art; And The C of collage: where what has been learned will be put into practice with the proposed exercises. You can use the cut-out material from the last few pages and have no excuse to start today. Long live collage!
