Thin strips of paste (5)
I believe the answer is:
tapes
'thin strips' is the definition.
'tapes' can be an answer for 'strips' (tape is a kind of strip). I am unsure of the 'thin' bit.
'of paste' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'paste' anagrammed gives 'TAPES'.
Can you help me to learn more?
(Other definitions for tapes that I've seen before include "Magnetic strips for recording" , "Records - strips of material" , "Bands of fabric" , "A spate of magnetic records" , "Recordings" .)
