My own efforts at melted crayon art for our daughter. Board is the normal backing to the picture frame. Painted with white chalk paint. Letter and umbrella blanks cut out of cardboard and the rest is obvious from the pics.
Melted Crayons combined with pictures. it would also look cool to put only black at white pics in the middle.like the color exploded from the pictures>>>>>> or if you did shades of black grey and white crayons with black and white pictures
