Interesting flat, 2D models?

[fncll]

I'm going to be sending origami pieces along with a BUNCH of letters. I'm looking for the best models that can be mailed flat. Obviously there are many traditional folds, but what else might you suggest? Incidentally, I'm not looking for modulars---I have a lot of them in the form of wrings and wreaths---though 1-2 pieces stars or the like are welcome...

Thanks in advance for any suggestions!

tesselations maybe?

There are dozens of stars which comply with your criteria.

I didn't think of some tessellations. I am using some stars as well...but hoping to find other interesting models as well. Some recommendations from the O mailing list include:

Diaz/Wu T-Rex (recipient can inflate)-- and maybe some others from Origami Essence and:

Trumpeting elephant
Hajime's dahlia
Fuse's reticulating lizard (I think that's what it's called)
Kasahara gorilla (from 1/2 square divided along diagonal)
Paul Jackson has two monkeys (from latest animal book)
Lang's dog (named for a German city tho I'm forgetting now which city it is. Sorry)
deg's howling coyote/wolf w bandana at neck
Snowflake (make this from translucent paper) I'm forgetting whose model right now but everyone was making it last couple years... It starts from a hexagon
Wreaths w crane heads (Petty book)
Simple fish (fun from funky patterned paper)
Sok's flat fish (I think that's what he called it...

Kasahara's rabbit maybe?

Edwin Corrie's puppy looks awesome.
