DIY terrarium Posted on March 29, 2012 by Tegan Howard 0 Reblogged from Madey Edlin: Start with about 3/4 inch sand. Add just enough water to make the sand moist. Pat down the sand level. Add a layer of rocks. (We used shiny rocks collected at the beach) Then a layer of dirt. Plant small cute little plants. Succulents are my choice. Yay!
