Absorbent cloth covering right garden tool (6)
I believe the answer is:
trowel
'garden tool' is the definition.
(I've seen this in another clue)
'absorbent cloth covering right' is the wordplay.
'absorbent cloth' becomes 'towel' (I've seen this in another clue).
'covering' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'towel' placed around 'r' is 'TROWEL'.
(Other definitions for trowel that I've seen before include "Beaten egg dish" , "Platsterer's tool" , "Something to help gardener" , "Scoop-shaped tool with short handle" , "small digger" .)
