Stroked soft material (4)
I believe the answer is:
felt
This clue might be a double definition.
'stroked' is the first definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Maybe you can see a link between them that I don't see?
'soft material' is the second definition.
Can you help me to learn more?
(Other definitions for felt that I've seen before include "It's reckoned" , "Sensed - beret material" , "Baize-like cloth" , "Fabric - perceived by touch" , "Soft fibrous material usually under carpet" .)
