St. Patricks's Day Ideas

Hi,
I’m a ones teacher at a preschool. I just needs ideas for phrases, or cute little sayings that include “ones” in them, or “one”.
I decorate the windows according to season with these.
For March (St. Patricks day) I put “can’t find anyONE luckier!”. Currently I have on the window “our class is ONE-derful!” With their hand prints on the window.

Ideas? thanks!
Also, if you know any quick and easy crafts/art for one year olds, that’d be great!! : )

We have a ONE-perfect little class. We have ONE an award for being the nicest class.
Something encouraging
It can be cheesy
