My personal preference is for Adobe Illustrator. I've been using it for a long time and am comfortable with it. I prefer a vector graphics program over a raster graphics editor like Photoshop. Depending on the airframe I usually draw a quick top/side/bottom view and work filling them in with my designs. The vector files also provide me with the ability to dump some elements or graphics to my plotter or make a full size template to cut covering.
Illustrator is kind of pricy so you may want to look for a cheaper alternative. Older versions of Corel Draw can usually be found reasonable and an open source alternative is Inkscape. Good Luck with you designs.
