Wall hanging concealed in embarrassment (5)
I believe the answer is:
arras
'wall hanging' is the definition.
(arras is a kind of wall hanging)
'concealed in embarrassment' is the wordplay.
'concealed in' indicates the answer is hidden within the clue.
'ARRAS' is hidden within 'embarrassment'.
(Other definitions for arras that I've seen before include "Tapestry; WW One battle" , "Wall hanging of heavy woven fabric" , "Tapestry wall hanging" , "Work of art" , "Tapestry; French town" .)
