Peaceful child initially swathed in patterned cloth (6)
I believe the answer is:
placid
'peaceful' is the definition.
(I've seen this before)
'child initially swathed in patterned cloth' is the wordplay.
'initially' says to take the initial letters.
'swathed in' is an insertion indicator (swathe can mean to wrap).
'patterned cloth' becomes 'plaid' (I've seen this in another clue).
The initial letter of 'child' is 'c'.
'c' put into 'plaid' is 'PLACID'.
(Other definitions for placid that I've seen before include "Calm and free from disturbance" , "Tranquil, even-tempered" , "Still - US lake" , "Calm of nature" , "Calm and not easily upset" .)
