Both sides in the Rugby like nice fabric material (8)
I believe the answer is:
terylene
'material' is the definition.
(Terylene is an example)
'both sides in the rugby like nice fabric' is the wordplay.
I cannot quite understand how this works, but
'both' could be 't' (I've seen this in other clues) and 't' is present in the answer.
'like' could be 'y' (similar in meaning) and 'y' is found in the answer.
'sides' could be 'rl' (I've seen this in other clues) and 'rl' is located in the leftover letters.
This may be the basis of clue (or it may be nonsense).
(Other definitions for terylene that I've seen before include "Synthetic fibre" , "Fabric of polyester fibres" , "synthetic stuff" , "Synthetic material" , "Polyester fibre" .)
