It's pretty carefully drawn (4)
I believe the answer is:
bead
'it's pretty carefully drawn' is the definition.
I can't judge whether this defines the answer.
'it's pretty' is the wordplay.
I cannot really understand how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found in the answer.
'pretty' could be 'bad' (similar in meaning) and 'bad' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bead that I've seen before include "Small ball with a hole through the middle" , "A bit of the rosary" , "Round piece of glass, etc" , "Drop of moisture; holed piece of glass" , "Part of a necklace" .)
