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.
Another take on crayon art. I have begun to see these pop up from time to time, this is making more than just runny melted crayons and I liked it. I have a lot of old crayons so there maybe something to this new art genre!
Shave crayons in whatever color/pattern onto a canvas, cover with wax paper and iron the whole canvas! The crayons will melt, creating your masterpiece!! Gonna have to try this one! ... Not my favorite piece of art, but I think if you used a blow dryer with the wax paper it would look better... worth trying.
