Resurrection garden basket. I bought my basket, plastic liner and plants at our local garden center. I chose a palm plant and a low growing grass type. I used a black plastic 3" pot laid it on its side and covered it with spanish moss for the tomb. Placed a rock at the opening and extra small ones as a path. We picked sticks up in the yard and broke them to size and used colored thread to secure them together.
