Flat rockery: You can find a piece of cardboard, cut it open with scissors-stick the cardboard into the desired rockery shape-and then stick newspapers on the cardboard one by one-and then stick it on the rockery with a brush or green paper as decoration-to complete the production of flat rockery.

2. Rugged rockery: find a piece of cardboard, cut it open with scissors-glue the cardboard into the desired rockery shape-nail the cardboard with uneven holes-paste the crumpled newspaper layer by layer until you are satisfied-paste it on the rockery with a brush or green paper as decoration-thus completing the rugged rockery production.
