Here is a simple way to reuse juice cartons that cant normally be recycled. Younger children will need the preparation work done for them.
You will need:
Tetrapak carton (long-life fruit juice, UHT Milk cartons)
Felt tip pens
Acrylic varnish (optional)
Make a hole in one of the two big sides of the carton and cut away the side. Make a few holes in the remaining big side. These will form drainage holes in the base of your pot.
Paint the pot with white paint and leave to dry. Decorate with felt pens. We drew on stars and moons but you could draw flowers or anything else you fancy. An optional coat of varnish will make the pot more hardwearing, particularly if you plan to use it outdoors.
