A terrarium is a fun and easy way to incorporate plants into your décor with minimal maintenance. Closed terrariums need less watering because the moisture is locked inside to create a miniature greenhouse, but it really comes down to personal preference. LAYERS, LAYERS, LAYERS! Create visual interest by layering different sands, stones, and mosses – then add soil & plants – and Viola! This class is $45 per terrarium and includes all materials & plants.
