Viewed tapestry essentially covered in wool - naturally (4)
I believe the answer is:
ewes
'wool naturally' is the definition.
I can't tell whether this defines the answer.
'viewed tapestry essentially covered' is the wordplay.
'viewed' becomes 'we' (I can't explain this - if you can you should believe this answer much more).
'essentially' means to look at the middle letters.
'covered' is an insertion indicator.
The centre of 'tapestry' is 'es'.
'we' placed inside 'es' is 'EWES'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ewes that I've seen before include "members of flock" , "She-sheep" , "Adult sheep" , "Females in the flock" , "Female sheep" .)
