Chicken wire, fencing, dance posts (Kirkstall LS6)

As per my other listing I need anything I can use to stop the dozen or so noisy, disruptive kids from using our front lawn as a play area. The parents don't help and we cannot use our living room when they're not at school, the council have been no help and we recently moved and currently can't afford to fence it off so anything that you've got going that would help would be fantastic.
