Here is a cheap little project that gives good results and is easy enough for kids to enjoy.
Step 1: Material
A picture you like
A computer with a printer
Glue stick (good quality)
Foamboard or cardboard
Step 2: Adjust Brightness and Contrast
Step 3: Stick It!
Step 4: Start Painting!
2.Then, give an extremely light coat of the lightest color over the face. It doesn`t matter if the color is not uniform at this point.
3.Start painting over the details with the darkest color. Don't paint unflattering lines, like big creases, blemishes, unibrows, and giant moles. You can also embelish the picture as you wish, trimming off a milimeter or two of the contour of a face to make it slimmer, or elongating eyelashes and adding details to hair. The nice thing with paint is that you can`t go wrong! You can always correct a shaky line or a blotch by adding another coat of color.
4.Once you painted over all the details, put on a second (and probably third and fourth) layer of the palest color to hide the original picture and to make the color uniform.
