Bit of needlework (6)
I believe the answer is:
tattoo
'bit of needlework' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tattoo that I've seen before include "Design worked on skin" , "Indelible decoration on skin" , "Military evening signal" , "Military call and design on the skin" , "Skin inking" .)
