Lego Party Table Decoration Centerpiece Supplies (1)
- 3 Empty Clean Milk Cartons
- 1 Flat empty box
- Primary Acrylic Paints
in yellow, blue, green and red colors
- Milk carton caps, about 40-45 (depending on the size of your boxes)

Lego Party Table Centerpiece Decoration Directions (1)

Step 1. Cut open milk carton. Remove the milk cap and cut off the plastic spout so that there is a hole flush with the carton. Rinse the carton and dry well.

Step 2. Fold the sides of the carton in and close off using hot glue or tape.

Step 3. Using acrylic paints from the craft store, paint the boxes in bright primary colors like green, red, blue, and yellow.

Step 4. Using a hot glue gun squeeze a generous amount of hot glue on the inside of the milk carton caps. Place the caps on the boxes and the excess glue will slowly ooze down the sides of the caps onto the milk carton and help secure the caps in place.

Step 5. Here is a picture of the caps glued in place. Once all the caps are glued on, paint another layer of acrylic paint on to the milk cartons.

Step 6. Paint the boxes and caps several times (hint: lots!) and let dry between layers. You may need to do this 3-4 times to cover the printing and images on the milk carton completely. Make sure to let the paint dry between layers. Once done, place the large Lego pieces in the center of the Lego Party table together with the Birthday Child’s favorite Lego pieces for a fun, festive Lego decor! Add in the name of the Birthday Child using Lego Letters Name Sign. After the party is over, use the sign over the door of the Birthday Child as a keepsake.
