Light Cover- Use one that is attractive, clear and free of cracks or chips. Other vessels will work too! Just be sure they are not toxic to your plant and that you can securely hang it.
Plant- Some type with a short root system and that doesn't need excellent or rapid drainage. Also, pick one that will not outgrow your terrarium too quickly. I used a clipping from a Jade plant because they are easy to propagate, but it will grow somewhat quickly.
Sterilized Soil- Either start with fresh potting soil, or sterilize used soil. Just be sure it has a healthy percentage of vermiculite or perlite. You need to sterilize used soil to get rid of any fungus or bacteria that would kill your plant. To do this pre-heat oven to 250 degrees. Lay soil about three inches deep in a cookie sheet/cake pan. Bake for about an hour or until soil is 150 degrees. Do NOT overcook, this could release toxins in the soil that will harm your plant.
Odds n' Ends- Rocks, seashells, rounded glass, marbles, or other natural artifacts that will increase drainage.
Hanging Material- rope, hemp or something of the like. You will need a ceiling hook too!

Watering your terrarium will depend greatly on the plant you select and how you managed your drainage in the vessel. So just be attentive to your new friend until you know what it likes.
