And not knowing Len Evans' thoughts, principals produced a little decoration (6)
I believe the answer is:
anklet
'a little decoration' is the definition.
'anklet' can be an answer for 'decoration' (anklet is a kind of decoration). I'm unsure of the 'a little' bit.
'and not knowing len evans' thoughts principals' is the wordplay.
'principals' indicates taking the first letters.
The first letters of 'and not knowing len evans thoughts' is 'ANKLET'.
'produced' acts as a link.
Can you help me to learn more?
(Other definitions for anklet that I've seen before include "Fetter" , "Foot ornament" , "Ornamental chain" , "joint protector" , "leg chain" .)
