Design is laced another way (5)
I believe the answer is:
'design' is the definition.
(decal is a kind of design)
'laced another way' is the wordplay.
'another way' is an anagram indicator.
'laced' is an anagram of 'DECAL'.
'is' acts as a link.
(Another definition for decal that I've seen is " Transfer - laced (anag)".)
