We've created these jolly mini terraniums in jam jars which will brighten any shady windowsill, or could be slightly upscaled in a Kilner jar or cafatiere. They could even be suspended with wire to hang from a Velux window or roof lantern. An odd number of jars is sure to look better than one.
You will need:
A selection of jam jars or other glass vessels
Paint suitable for metal
Multi-purpose or house plant compost
Young plants such as ferns or spike mosses
Shell
Spoon
Bradawl
Sandpaper
Plant mister
Decorative items to adorn lid (optional)
