You will need:
an old teacup or two
a small amount of soil
some moss (a few tufts)
Take a walk around your local area for moss, and you will be surpised just how much there is around you, and how many varieties you will find. Look in moist places or difficult-to-grow-in places, like between pavers. Moss seems to have this 'i can grow anywhere and i will not die' attitude, which is why it's great for those of us born without green thumbs.
1. Fill your teacup with soil to roughly 1cm or 1/2 inch from the top
2. Top with moss, placing the tufts in so they are just firmly packed and you can't see any soil. Using a few varieties of moss looks effective, as do any tiny plants that may have come along for the ride.
Your moss 'garden' should grow pretty much anywhere but on the window sill or front step is best so they can get some sunlight. If you have some tiny plants in yours they will definitely want sunlight. Since the cup doesn't have holes in the bottom for water to escape, you won't need to water your 'garden' often. Just check to see it is moist once every 1 or 2 weeks. If it seems a bit dry give it a little bit of a drink (I water mine once a week). Too easy!
