Working in glitzy items around the edge (8)
I believe the answer is:
blending
'working in glitzy' is the definition.
I can't judge whether this definition defines the answer.
'items around the edge' is the wordplay.
'items' becomes 'bling' (I am not sure about this - if you are sure you should believe this answer much more).
'around' indicates putting letters inside.
'the edge' becomes 'end' (I've seen this in other clues).
'bling' going around 'end' is 'BLENDING'.
Can you help me to learn more?
(Other definitions for blending that I've seen before include "Mixing different ingredients into one" , "in colour-coordinated harmony?" .)
