Picks woven carpet to cover interior of villa (7)
I believe the answer is:
plectra
'picks' is the definition.
('plectron' can be a synonym of 'pick')
'woven carpet to cover interior of villa' is the wordplay.
'woven' indicates anagramming the letters.
'to cover' means one lot of letters goes inside another.
'interior of' means to look at the middle letters.
The middle letter of 'villa' is 'l'.
'carpet' anagrammed gives 'pectra'.
'pectra' placed around 'l' is 'PLECTRA'.
(Other definitions for plectra that I've seen before include "Plucky types" , "Guitar picks" , "Bits of plastic maybe" , "Guitar pickers - carp let (anag)" , "Parts for harpsichord" .)
