I think it would be really cool to change the view of the backyard cinder block wall. It will take a while for plants to grow.
It would be neat to plaster it out and press a complete, brightly colored table setting into the wall before the plaster set. One table setting per family member in different sections of the fence, different color setting per person.
Or imagine a tiny little tea cup set pressed into it. Anything would be better than brown. I might have Zane take the chalk to it next week.
