Grandma eager to find cloth (7)
I believe the answer is:
nankeen
'cloth' is the definition.
(I know that nankeen is a type of cloth)
'grandma eager' is the wordplay.
'grandma' becomes 'nan' (nan can informally mean a grandmother).
'eager' becomes 'keen' (I've seen this before).
'nan'+'keen'='NANKEEN'
'to find' acts as a link.
(Other definitions for nankeen that I've seen before include "Hard-wearing fabric, originally from China" , "Buff colour(ed cloth)" , "Yellowish cotton cloth" , "Buff colour" , "trouser material" .)
