Fell making twitcher’s shelter (4)
I believe the answer is:
hide
'shelter' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for hide that I've seen before include "Flog" , "Keep under wraps" , "Take cover - skin" , "Screen; skin" , "Animal's tough skin" .)
