With a good set of thumbnails complete, it's time to choose an idea. Of the 4 designs that you have made, which of these is the one that you like the best? Whichever one you prefer, you need to develop it in to a more smooth, clean and large rough. It's ironic that it's called a rough, because it shouldn't be rough! It's going to be the pattern that you use to draw from so the more smooth it is on the rough, the more smooth it will appear as a vector. After you have drawn the design, grab some colored pencils and color it. Once the rough is complete and colored, your good to move the next step... importing it to the computer.
