Kate Middleton’s Royal Engagement with In-Laws at Dulwich Art Gallery [SLIDESHOW]

Kate Middleton, Duchess of Cambridge, joined the Prince of Wales and the Duchess of Cornwall at a Prince's Foundation for Children and the Arts event in Dulwich Picture Gallery.

Although Prince William was away on other duties, Kate and her in-laws ambled through the south London gallery and participated in some of the creative classes.

The Children and the Arts charity was launched by Prince Charles at the gallery in 2001 as a pilot scheme before it became an independent charity in 2006. It is an educational charity which provides access for young people who would otherwise grow up having had no, or very limited opportunity, to engage with the arts.

Kate shares a deep interest in art and is a patron of the National Portrait Gallery and the Art Room.

It was the first time the Duchess of Cambridge had joined her father-in-law, Prince Charles on a visit to one of his charities.

Hundreds of cheering schoolchildren greeted the royals in bright sunshine.

They took part in a class with children at the art education centre to make self-portrait collages. Kate cut out a heart shape from lace before putting it on her picture of a face in side profile.

She was wearing a dark grey Orla Kiely dress with black pattern detail.
