Forgive me for this super late post. In preparation for our Cabo trip, I made portable LEGO kits for Parker and Elijah so they would have something fun to play with on the plane. This is an easy project and you can find a full tutorial over on the Mama. Papa. Bubba. blog. Jen's instructions are easy to follow so I'll just share my buy list with you.
Metal lunchbox (I found these in the dollar section at target)
These kits were a big hit with the boys on the plane and throughout the trip. I'm so glad I made them!
