A boy in my class a couple years ago gave these as little Valentines made out of melted crayons. He said, For Crayon Out Loud, Happy Valentines Day... could also say, You COLOR my world! Use silicone cups to melt them in. baha love it
Use duct tape for words. Place crayons on top. Blow dry on high heat till crayons melt. Blow dry side to side to blend colors. Slowly remove duct tape to reveal words. I've seen the crayon thing before, but love the duct tape idea!
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.
