surface protection like newspaper or plastic (shower curtains are great for covering surfaces then washing off and reusing later)
Step 1: Pick out the colors you want to use and line them up or put them in a creative design.
Step 2: Use the glue gun to glue the design down. I suggest setting it up on the canvas and then removing a few pieces at a time and gluing down back down as you go. If you’re making a straight line glue first and last piece first so crayons won’t roll.
Step 3: Protect your surface with covering, hold the canvas at the angle you want the crayon to drip. If you are doing a special design it is better to melt it in the direction you want it to drip then let it dry before turning it because as you turn the canvas the crayons run in the direction you turn when they are still hot. Play around with settings on the hairdryer so you can control the splatter and the drip/running of the crayons.
TIP: think the colors through, use several of the same color if you want to get a good solid streak going down, using certain colors together make a muddy brown mix.
