Stripe on new sheets etc (5)
I believe the answer is:
linen
'sheets etc' is the definition.
(bed sheets might be made of linen)
'stripe on new' is the wordplay.
'stripe on' becomes 'line' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'line'+'n'='LINEN'
Can you help me to learn more?
(Other definitions for linen that I've seen before include "Cloth made from flax" , "Sheets, pillowcases etc" , "E.g. bedclothes" , "Sheets, tablecloth etc." , "Fabric, originally just spun flax" .)
