I've got a lephrechaun and a shamrock lined up....

Any other easy ones you guys might know?

There are several great rainbow balloons / hats. You could weave a pot of gold.
Are you doing decor or working parties?

If you working a party take lots of green turn everyone into leprechauns make green hats, dogs, cats, anything they ask for. . Don't forget green courage brackets with 4 pedals & a stem!

OH Shucks I was gonna chime in with a pot of gold,but Jewls beat me to it.

shamrocks, leprechauns, pots of gold, rainbows, green beer in a glass, green martinis, belt buckles, top hats, green flower bracelets, lucky frogs (hold onto them or you'll get a pinch!)

Any examples guys???
