I once made a terrarium with a friend. She brought over a kit and showed me the ropes.
It was easy, beautiful and featured adorable mini people, but it also died pretty quickly (I forgot you actually have to water plants). Then I came across Miniscapes.
It promised to teach me the skills to maintain a healthy, happy terrarium. Naturally (pardon the pun), I was sold.
Although I’m yet to actually try to build another terrarium, I’m still impressed with Clea Cregan's hardback. It’s made up of pastel pretty colours, clever photography and idiot-proof guides.
Perfect for those not-so-bright people who forget plants need water.
