Adobe Illustrator CS5
I always try to expand my working area. Despite I use Adobe Illustrator for many things, I had never tried to design a t-shirt, but one day I thought trying to keep to a limited number of colors would be a good exercise. I had to think about the design carefully and search about halftones. Then, I had to pick the colors I was going to use, and readjust the design to them. I have to improve yet, but I had a very good time learning and working. You can see and vote my designs here if you want to.
