Note woollen creation round toddler's head (8)
I believe the answer is:
crotchet
'note' is the definition.
(musical note)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for crotchet that I've seen before include "In music, it has quarter the time value of a whole note" , "as mark scored" , "Peacock's castle" , "Two quavers as one note" , "A note in music equal to half a minim" .)
