Weaver finding support (6)
I believe the answer is:
bottom
This clue is a double definition.
'weaver' is the first definition.
(Bottom the Weaver from A Midsummer Night's Dream)
'support' is the second definition.
(the base or support of something)
'finding' is the link.
(Other definitions for bottom that I've seen before include "Shakespearean - rear" , "Lowest part or underside" , "far end" , "Rump" , "Crack" .)
