Tracey Emin promotes BBC Four

A detail from the Tracey Emin design

Artist Tracey Emin, recently described as someone who "could not think her way out of a paper bag", has designed the invitations to the launch of the new digital channel BBC Four.

The Corporation is sending out 1,500 handkerchiefs adorned with her designs to promote its new arts and cultural channel.

Recipients will be invited to the launch party, which will take place in a former rug factory in east London on 28 February.

Emin's My Bed caused a storm when it went on show

The invitations take the form of a small brown cardboard box containing a card, with the Emin-designed handkerchief tied round it.

On it, Emin has written: "BBC Four: Everybody needs a place to think."

The invitation card says: "Please bring this invite with you otherwise you're not going to get in, love Tracey."

A BBC spokeswoman said that the artist had been paid a "nominal fee" to produce the work.

Massow: Criticised artists' "bloated egos"

Emin became a star among Young British Artists with My Bed, her shortlisted entry to the 1999 Turner Prize, later bought by Charles Saatchi for £150,000.

The installation comprised an unmade bed, surrounded by underwear, vodka bottles and a used condom.

Emin was one of the artists mentioned in a recent attack on conceptual art by Ivan Massow, chairman of the Institute of Contemporary Arts.

In the New Statesman he described much contemporary art as "the product of over-indulged, middle class (barely concealed behind mockney accents), bloated egos who patronise real people with fake understanding".
