We hardly have enough money for blu tak now. No chance of funding for after school clubs. Actually we have never allocated money for after school clubs, we would expect the parents to pay for anything that costs money eg. sports coaching. We teachers lead forest schools sessions in our school and recruit volunteer parents or members of the community to share their skills in special projects such as the cob oven you mentioned. So sorry to disappoint, building an oven is not high on the list of priorities, we need to buy exercise books first!
