Great recipie I found on a bling I read Jello play dough for St. Patrick's day I decided to use lime green jello play dough. That pesky leprechaun made my play dough smell like lime.

I had the students make a pot that I could put leprechaun gold in (gold glitter) then they mixed the glitter in. Next I taught them how to make a Celtic knot shamrock from a snake. Then let them loose to create.
