We used old shoeboxes, green tempera paint, shiny rainbow stickers, glue, glitter, and oil pastels. Basically they each painted a box, I cut a hole in the box with an xacto knife (for the leprechaun to climb in), and then they finished decorating the box with stickers, oil pastels, and glitter. We plan to dangle gold mardi gras beads from the box to lure the leprechauns. They like gold, of course!
I don't know if this might be one of those signs (you know, where later everyone is like, "ah, yes, the leprechaun traps...I knew then.") that I'm losing it, but I have really enjoyed watching and assisting the girls as they've made these. I think...I think I might believe. Happy St. Patrick's Day!
