Have you seen the post box toppers that have been appearing in Dulwich recently? They are crocheted by ‘guerrilla yarn bombers’ and placed on top of post boxes to brighten the neighbourhood and delight passers-by. Every topper is different and some even have lights inside. The Royal Mail has welcomed the toppers, saying 'We love seeing the various post box toppers that that different groups have showcased in communities across the UK'.
