Drawing toy signage occasionally (5)
I believe the answer is:
tying
'drawing' is the definition.
('tie' can be a synonym of 'draw')
'toy signage occasionally' is the wordplay.
'occasionally' indicates alternate letters.
'toy'+'signage'='toysignage'
The alternating letters of 'toysignage' are 'TYING'.
(Other definitions for tying that I've seen before include "Linking" , "lacing" , "Scoring the same" , "Restricting" , "Binding, fastening" .)
