Watch: How do you make snow-window art?

A couple who have been helping to support the homeless through their snow art share their tips for making the wintry designs.

Tom and Keri run Christmas business Snow Windows, which involves painting snow art on windows.

The couple, from Sandhurst, in Berkshire, have collaborated with homelessness charity Crisis to create a snow window design for a string of their charity shops, including in Muswell Hill, north London.

BBC London's Eric Anderson was put through his paces to see if he could become a snow-window artist.
