Springy like the laciest creations (7)
I believe the answer is:
elastic
'springy' is the definition.
(similar in meaning)
'the laciest creations' is the wordplay.
'creations' indicates an anagram (I've seen 'creation' mean this).
'laciest' is an anagram of 'ELASTIC'.
'like' is the link.
(Other definitions for elastic that I've seen before include "Able to stretch" , "Flexible rubber strip" , "Laciest (anag.)" , "Like some bands" , "Stretcher" .)
