Position of soft, delicate fabric (5)
I believe the answer is:
place
'position' is the definition.
(place is a kind of position)
'soft delicate fabric' is the wordplay.
'soft' becomes 'p' (musical abbreviation for 'piano').
'delicate fabric' becomes 'lace' (I've seen this before).
'p'+'lace'='PLACE'
'of' acts as a link.
(Other definitions for place that I've seen before include "Put in - winning position" , "Scene; put" , "square?" , "Locus" , "Situation" .)
