The promises pattern is from Pressed for Time Quiltworks by Mary Hubka.
She makes her patterns for 8 "sweet treats" or fat quarters. I doubled the size cause I like to make my quilts a little bigger, for 2 to snuggle under. You can google Pincushion Boutique and look at their website and it will list all of her patterns. I am making a very similar one for my son in a queensize from a different pattern. I can't find my book at the moment. I'll look and give you the name of that one as well.
