Here are some I made earlier :). When I went about making these I thought they would be much more to it than what it is, they are just so easy to make and look beautiful.
All you need is:
A layer of pebbles at the bottom of your jar( or any clear container)
A layer of charcoal( i used crushed up artists charcoal)
A layer of soil
Make holes in the soil to plant the plants of your choosing( usually mini succulents or ferns..Found them very hard to get tho)
Pack soil tight around them
Add moss and/ or decorative items
Spray with water and leave open and dry overnight, then spray again wait until water has soaked through and place lids.
And now you have a terrarium :)
There are many ways of making terrariums. Check out my other blog Popcraft for an amazing terrarium artist Paula Hayes.
