Passed fingers over material (4)
I believe the answer is:
felt
I believe this is a double definition.
'passed fingers over' is the first definition.
(to pass one's fingers over something is to feel it)
'material' is the second definition.
(felt is a kind of material)
(Other definitions for felt that I've seen before include "investigated in touching way" , "Rather thought; a cloth" , "Laid hands" , "Experienced, say, emotion" , "Soft fibrous material usually under carpet" .)
