Just a thought that you may well be interested in for your schools that i’ve got from Send a Cow … Its a brilliant idea - using the Bag Gardens! I feel its a really eco-friendly concept and I’ve been working with my children to create some for our garden.
Think what my children enjoy is painting the bag all sorts of colours, shapes and design and the hard gardening gets left to me 
But that could be a project run over two weeks for any school, or as additional offer to a yoga school to bond with your groups and members?
What do you all think about this activity? Thank you send a cow - a donation made to you from me jess x P.s - Send a Cow actually have more information about the Bag Gardens already being introduced in schools. For more Information : sendacow.org.uk
