Im fairly certain lacewing is not a ino bird carrying cinnamon. If you look back over the available history of the lacewing, there are arguements about two theories for its origin.
One theory is that there was a genetic cross over in a mating between ino birds CARRYING but not SHOWING any markings. Albino masks most mutations except for yellowface. However, the thought is that when the genetic crossover occured, it somehow weakened the ino gene or strengthened the cinnamon gene, allowing some faint markings of a light cinnamon colour to appear on what they dubbed the 'cinnamino'.
Another arguement is that a lacewing is neither albino or cinnamon, but a new mutation carrying phenotypical aspects of both - leading to the common confusion that it is either a crossover or a bird that is ino and also carrying cinnamon.
The only evidential data i have found but not been able to confirm is that there was a breeder who was a scientist or some such, and being curious about lacewings and believing it to be a genetic crossover (something like a 1 in 1000 chance of crossover, possibly 10,000 not sure but its rare) he proceeded to breed a large number of albino's who carried cinnamon. Apparently after a few generations, a lacewing appeared and he was then able to breed further lacewings from that bird.
There is an even vaguer and far less substantiated claim that a breeder was able to 'breed out' the wing markings in his lacewings. This has been countered with the idea that he used albino's to 'weaken' to colour, or so he thought. In actual fact he simply replaced the lacewing gene with inos, and breed out his lacewing stock, not the colour itself.
My suggestion for breeding a creamino lacewing would simply be to breed a lacewing male to a yellowface type 2 female. All your female chicks will be lacewing, and they have a 50% chance of inheriting the mothers YF2 - giving you the creamy lacewing of your dreams..
Alternatively, just get a green series lacewing... buttercup yellow with faint cinnamon markings
