Experienced in soft fabric (4)
I believe the answer is:
felt
I believe this is a double definition.
'experienced' is the first definition.
('feel' can be a synonym of 'experience')
'soft fabric' is the second definition.
(I've seen this before)
'in' is the link.
(Other definitions for felt that I've seen before include "Ran one's hand over" , "Considered" , "checked by hand" , "material for a fedora" , "Touched; a soft material" .)
