Didcot Library has a display of BBC/Poetry postcards. They are free, so I took 2 and am planning to use these for my letter on Home Education to our local MP Ed Vaizey. Now I have written this I am honour-bound to get going with writing and sending it.
Do look in your local libraries for these, they have striking designs on the front and a snippet of poetry on the back and front.
Gold star for Didcot Library, it has such a lovely load of brand new books to enjoy.
