Quilters' get-together (3)
I believe the answer is:
bee
'quilters' get-together' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bee that I've seen before include "competition" , "Busy person" , "Honey-making insect" , "In one's bonnet, it's a persistent idea" , "In one's bonnet, it's an obsessive idea" .)
