I think treasure hunts should happen for all occasions, and I think my children agree! This St. Patrick's Day treasure hunt was so much fun to do as a family and got us outside and moving around on a chilly March day.
We first cracked our walnuts, being very careful to keep our half-shells intact. The kids helped by eating the walnuts! After we opened them all we painted the shells gold with acrylic paint. Once dry, I sent the kids away while I filled the shells with goodies and sealed them back up with a few dots of hot glue.
