Corner location houses first class new section on cotton fabric (8)
I believe the answer is:
nainsook
'corner location houses first class new section on cotton fabric' is the definition.
(I've seen this before)
'first class new section on cotton fabric' is the wordplay.
'first class' becomes 'ai' (An - top quality).
'new' becomes 'n'.
'section' becomes 's' (legal abbreviation).
'on' means one lot of letters goes inside another.
'cotton fabric' becomes 'nook' (I can't explain this - if you can you should give a lot more credence to this answer).
'ai'+'n'+'s'='ains'
'ains' going inside 'nook' is 'NAINSOOK'.
Can you help me to learn more?
(Other definitions for nainsook that I've seen before include "Fine soft cotton fabric" , "Corner location houses first class new section on cotton fabric" , "Material" .)
