Select Paint from the Results screen to open the Paint program. What appeals to me in making your own grid is that you can have as many or as few divisions to the grid as you want. After working with a gridded viewfinder with a 3 x 4 division, you may find that you are getting better at mapping an image to your canvas and you can create the gridded viewfinder with fewer divisions.
As you gain more experience at drawing what you see, you may not have to use a viewfinder at all.
