To help understand abstract art a little better, make your own abstract image.  Begin by picking two or three of your favorite colors of construction paper.   

Decide on one shape you think would be best for your image.  Easy shapes to cut out are usually very angular:  squares, triangles, rectangles, hexagons, etc.  Once you have decided on your shape, cut that shape out of all your construction paper colors but vary the sizes (triangles are shown in the example).  Make some small and large shapes for variety in your image.   

Next, place your shapes on a white background piece of paper.  Begin moving them around - don't try to make a picture of anything, just find an order to you shapes that you seem to like.  Try overlapping your shapes, turn them around, use your imagination.  When you are happy with your arrangement of shapes, use small dabs of glue to attach the shapes to you white paper. 

For an added "kick" to the above image, circles of black paint were stamped on to create constrast - a vibration between light and dark. 

Hang your abstract image up in your room so you can look at it often.  Do you like the colors together that you chose?  Does the arrangement of shapes look good to you?  Did this help you to understand abstract artists a little more?
