You can simplify this terrarium quite a bit and you could just simply put soil in a wine glass then add your plants. But if you want maximum appeal and maximum health and lifespan for you plants you should use a standard terrarium set up like that shown in the drawing.
Put a few pebbles in the glass then add a thin layer of activated charcoal, a thin layer of spaghnum moss, then your soil. On the very top of this diagram I have put moss. This is just for looks. I recommend that if you are doing a succulent or cactus terrarium you put a layer of sand. This is what Jenny did in her wine glass terrarium.
The pebbles will accumulate the water. The charcoal will purify the water and the Spaghnum moss will prevent the soil from slipping down into the water around the pebbles and retain some of the water in a healthy way. It will keep it crisper and neater looking. This will also keep the roots of the plant(s) healthier. With an open container terrarium like this all of these steps are optional but this is the optimal set up for health and longevity.
This picture shows the layer of sand at the top which is perfect for the type of plant.
And one of the best things about this is that you can use some creativity to add little touches. Colored quartz pebbles, ribbons, a small card, tiny miniatures, or you can paint right on the glass or the base of the glass like this.
For her terrariums Jenny used Gardener's Gold Organic Potting Soil
Miracle Gro Spaghnum Peat Moss
And Black Diamond Activated Charcoal

Haworthia Collection - 5 Plants - 3.5 - Haworthias are a genus of small succulent plants confined in the wild almost exclusively to the Republic of South Africa. The charm of Haworthias is in their small size, ease of growth, and the almost infinite variation of their delightful leaves. Haworthias rarely require a pot larger than 4-inches in diameter making them ideally suited for a bright windowsill. Perhaps the biggest problem you will encounter when growing Haworthias is that they tend to be addictive! If you acquire more than one plant, you may find yourself wanting more and more. Haworthias are very easy to grow. Remember that Haworthias are succulents, so they require abundant bright light. They also require a well drained soil that approaches dryness between watering. It is best to fertilize only sparingly, using a water soluble houseplant fertilizer diluted to 1/4 strength, no more often than monthly during active growth, and not all if the plant is resting. Normal house temperatures ar fine. The collection of 5 different Haworthias you will receive are growing in 3.5" pots. They are similar to the ones pictured. They are 3-4 inches tall.
