Weaving linen up as cape (9)
I believe the answer is:
peninsula
'cape' is the definition.
(I've seen this before)
'weaving linen up as' is the wordplay.
'weaving' is an anagram indicator.
'linen'+'up'+'as'='linenupas'
'linenupas' is an anagram of 'PENINSULA'.
(Other definitions for peninsula that I've seen before include "the Balkans and Italy, for example" , "Large land-mass projecting into a body of water" , "land project" , "Headland" , "cape" .)
