i took note of the fact that you don't think adding borders to the elephants will work. that may or may not be the case.
lay out all the blocks in the way you had originally intended.
take a photo and post it. once we can see it, i'm sure you'll get lots of helpful suggestions based on blocks we can see next to each other.
this can be fixed. i'm sure of it. take a deep breath. it's going to work out. ;-)
