Another pinner says: I saw something like this at Michaels ! All you do is line crayons or colored wax at the top of a canvas. Then you burn the wax so it melts down the canvas leaving trails of color !
Crayon Art! Very cool. Tape off the white with Painter's tape. Then after melting crayons, place stencil over bottom, mark with toothpick/chalk and then paint black acrylic paint once stencil is removed.
