This is my abstract art that I have done, using The Gimp. First of all, I made zigzagged lines using the tool called Select hand-drawn region or you can press on F to select it. The lines are located at the top and bottom. I filled them in using the Bucket fill tool. Then I drew rectangles and squares using Select Rectangular Regions. I filled them in as well, using the Bucket fill tool. I also drew circles using the Elliptical tool. Then I filled the Circles in.
