Hide ones kid playing (7)
I believe the answer is:
doeskin
'hide' is the definition.
(thesaurus)
'ones kid playing' is the wordplay.
'playing' indicates anagramming the letters.
'ones'+'kid'='oneskid'
'oneskid' anagrammed gives 'DOESKIN'.
(Other definitions for doeskin that I've seen before include "Type of leather" , "Leather from deer" , "glove material" .)
