Mix together (2) parts Lavender with (1) part Lamp Black. Mix together (2) parts Lavender, (1) part Neutral Grey, and (1) part Snow White. Alternating between the two mixes, use a chip brush to pounce onto the canvas. (Switching between the mixes without cleaning the brush will help to blend the colors together.)
Transfer the provided spider web template onto the canvas using transfer paper and a pencil. Mix together (2) parts Lavender, (1) part Neutral Grey, (1) part Snow White, and (1) part water. Use a #1 script liner brush and the mix to paint in the spider web.
Using the darkest mix from Step 2 and a chip brush, pounce a vignette around the outside of the canvas.
Position the "Along Came a Spider" stencil from the Value Kraft Spider Stencil pack on the bottom right corner of the canvas. Tape down. With a cosmetic sponge, apply Jack-O'-Lantern Orange onto the stencil. Allow the paint to dry between coats.
Add a small amount of water to Lamp Black to make it more fluid. Using a script liner brush, add an outline of the watered-down Lamp Black along the right side and bottom of the lettering.
Transfer the spider patterns onto the canvas. Using a #2 round brush, paint the spiders and webs in Lamp Black.
