Some Things to think about, this will help you come up with ideas for a terrarium.
-Number of Plants: There are a few different things we can vary when making a terrarium. The first thing is the type and number of plants. A single plant terrarium can be very attractive and I call this a Zen terrarium. From there the number of plants can go up to fill any sized container.
-Types of Plants: And we have a stunningly wide variety of types of plants that we can use. These vary from carnivorous to succulents and airplants. How about flowering plants? You can just go for beauty or you can stick with a theme like a jungle theme or a desert theme.
- The Container: This is also a place where you can have a lot of fun. Just about any glass container can be a terrarium. Believe me when I say I have tried it. I even made a single plant terrarium inside a tabasco bottle! That tutorial is around here somewhere :) Flat containers, Wine Glasses (I have a tutorial on that too), Fish tanks, Even hanging globes. Wine glasses and how about a conch shell? These are all things that are terrariums. I have all the tutorials right here on my website! Yup. Have fun! Send me a pic.
- The Accents: You can add all kinds of interesting a fun little things to your terrarium to make it special. I have one here on my site that was made by a fan of the TV series LOST. It has a figurine of one of the characters in it. That is just one example. I have a whole page of terrarium accents right here. It will give you some ideas.
