If you want to make sure your soft pastel drawings don’t smudge once you’re finished, try using a spray fixative to ensure the pastel stays put!
In the center of a piece of cardstock, draw a rectangle measuring 1” x 1 ¼”
Cut out the rectangle using an exacto blade
Voila! You have a viewfinder!
If the orientation of your drawing/painting is square, just cut a square viewfinder!
