Here's a different poetry competition. The entries must be collaborative efforts between two people of different generations. One must be under eighteen. They don't have to be related, but it's fine if they are.
All the shortlisted entries will be made into 200 postcards, which will be given to the poets and the winners will also got book tokens. If I knew any children who could write poetry, I'd be having a go at this. Obviously they'd have to do pretty much all the work.
