Today's 'craft' is really drawing or doodling. Supplies you need are pens, pencils, markers, crayons, colored pencils, etc and something to draw on. Basically whatever you want to draw with and on. The suggested drawing is/can be designated as modern art. How can it be used? Well, just as a way to relax and draw...but you can apply the same technique to making greeting cards or postcards.
First, using a dark pencil or marker, doodle a line something like this one...
Next, fill in all the completed circles or ovals with bright colors similar to this example...
Finally, add some background shapes without the outlines similar to this example...
Just shapes and colors! The basic idea is to have fun and relax and doodle whatever pleases you.
