I have been wanting to try this for some time its on the long list of things to try. And its alot of fun kind of like putting a puzzle together, but more fun tear your own shapes. The first thing to do is to draw a shape on paper and cut it out, I did a bird.draw the size and shape to add to your page . cut it out with scissors, then figure out colors you want to use and tear pages with the colors out of magazine. then tear with your fingers in to shapes you want to fit your drawn bird, place and look it see if you like it , then glue it in place, you’ll get so that you guess the size pretty quick.
