Visit housebling.org.uk and simply type in your postcode, then get decorating with virtual outside wall lights and decorations - including snow! You can even have a play with famous landmarks like Coronation Street's Rovers Return (pictured). Afterwards share your designs on Facebook, Twitter or via email.
The site's association with Shelter highlights the plight of the homeless people at Christmas, offering you the option to donate after your decoration is complete.
