Our Experience Making A Homemade LEGO Costume

We try to make the kids costumes each Halloween.   This year, Lowes inspired us to “think outside the box” and with the help of a giant appliance box (Thank you handy shopping assistant Doug!!) and a couple of cans of spray paint as well as several smaller boxes we had Legos. Human Legos.

Lego blocks are one of our favorite things to play with. All. Day. Long. The kids absolutely love building and creating.

Red is my son’s favorite color. He’s thrilled with his costume – and I was thrilled with how easy it was to create. All it took was a short trip to my local Lowes.
