Prepare all your stuff

Draw some parallels lines with the ruler. Draw them at different distances.

Draw randoms forms that reminds of aztec prints. Use your imagination to do something pretty.

Use different size of tip to do smaller or bigger lines

Here are some of my favorite shapes, you can inspire you of these.

Chose a few color crayons

Color your aztec prints. Make sure there is not too much of the same color at the same place.

Now that you know how to make aztec prints you can make them everywhere you want to; on iPhone case, paper, notebooks, bags, walls, t shirts, agenda, etc …

Ps: I did these aztec prints really quickly so they aren't really pretty but if you take your time and you practice a little it will be really pretty. But don't worry it's simple and easy.
