Surprisingly deep, a cloth evenly folded (7)
I believe the answer is:
pleated
'folded' is the definition.
(pleating is a kind of folding)
'surprisingly deep a cloth evenly' is the wordplay.
'surprisingly' indicates an anagram.
'evenly' indicates alternate letters (even-numbered letters only).
'a'+'cloth'='acloth'
The alternating letters of 'acloth' are 'alt'.
'deep'+'alt'='deepalt'
'deepalt' with letters rearranged gives 'PLEATED'.
(Other definitions for pleated that I've seen before include "With folds sewn in" , "Folded and stitched" , "Gathered" , "Given creases" , "Folded and sewn" .)
