Soft cloth with unique edging in European city (6)
I believe the answer is:
prague
'european city' is the definition.
(capital of Czechia)
'soft cloth with unique edging' is the wordplay.
'soft' becomes 'p' (musical abbreviation for piano, 'soft').
'cloth' becomes 'rag' (rag is a kind of cloth).
'with' means one lot of letters go next to another.
'edging' says to hollow out the word (remove centre letters) (edging means the letters on the edges).
'unique' with its centre taken out is 'ue'.
'p'+'rag'+'ue'='PRAGUE'
'in' acts as a link.
(Other definitions for prague that I've seen before include "Czech Republic's capital" , "Gear up for this European city" , "Rather quiet" , "Capital city of Czech Republic" , "European capital" .)
