I made these signs for Halloween. I came up with the saying a couple years ago and made blocks and an upright little plaque thing. I thought the upright would be cute hanging on a wall by an orange ribbon or something.
I painted the wood orange, then put on a weathering/ crackle layer, you can buy cheap crackle medium at craft stores by the acrylic craft paint for $2-$4. Then when you apply the top coat, in this case, black it shrinks and cracks. It is water activated so I think next time I will water the paint down to hopefully produce larger cracks.
