This is a "copy" of artwork I had done when fingerpainting in Kindergarten. This shows how to preserve it and use it to decorate a child's room.
Total Time: 1 to 2 hours
lightweight white fabric
Tape art work to a window. On top of that, tape lightweight white fabric over the art work. Using embroidery pens (or crayons or colored pencils) trace the artwork and color using the same colors as used on the original art work.
Make a wooden frame using 1 by 2's. Screw the four sides together. Staple gun the fabric to the underneath side of the wooden frame.
