For our daughter's 5th birthday, we held a LEGO-themed party. A highlight of the party was the huge pile of 75 giant LEGOs. The giant LEGOs were made by painting cardboard moving boxes in the classic primary LEGO colors. They kept a dozen five-year-olds (and plenty of excited parents) occupied for a couple of hours. Building with the blocks was great, but, of course, knocking them down was even more fun.

Since DUPLO is twice the size of regular LEGO, QUATRO four times, and these blocks are about ten times that size, we've decided to call them DECCO. Just moved, and looking to reuse your boxes? Make DECCO!

Step 1: Supplies

Our supplies included:

  • 75 12'' x 12'' x 16'' boxes
  • paint matched to LEGO colors blue, green, red, and yellow
  • rollers and trays
  • masking and protective materials
  • tape
So cool!!
<p>I always wanted one of these when I was a kid, this is totally easy and awesome :)</p><p>Wondering how the design could be remixed so that we could also make ceilings with it! :)</p>
<p>Be safe kids these legos are dangerous ooooooooooooooooooo</p>
<p>Very Cool! I like how the boxes could still be used for storage.</p><p>For my son's 13th, we had a Lego themed party at a pizza place. We made plinths out of freshly washed Legos and put a brand-new minifig on each. It looked great.</p><p>(I put the Legos in a mesh lingerie bag, laid it flat in the top rack and washed them in the dishwasher.. I also do this when we get them second-hand).</p>
<p>I edited my post into the non-nonsensical. We put the Lego plinths into the corners of a commercially decorated cake from the supermarket. I like making my own, but knew I'd make myself into a nervous wreck if I had one more thing to do.</p>

<p>Those are giant blocks, but the are not Lego bricks. They do not have the interconnecting studs.</p>
<p>True. LEGO-colored cardboard boxes would be a more technically correct name. </p>
<p>I suppose you could use egg carton cups or paper ice cream cups, paint them, and glue or sticky tape them to line up and sit stacked if you would really like to have the interconnecting studs.</p>
<p>But you would have to cut corresponding holes in the bottoms of all the cartons, and all of them would have to be in the same place to be interchangeable. I think that would be entirely too much work for a not really accurate imitation. As they are, they are easy to make and a lot of fun for the kids. I was just pointing out they are not Lego. </p>
<p>Great work. As a person with experience I advice a further use for these boxes. Counting (how many of each colour, do we have more or fewer yellow and how many?), colour recognition, measuring (size of boxes,total size of each row, cube, etc.). Writing, tallying, charts, etc. You get the point. Love it.</p>
<p>She's 5 already? Wow, time flies!</p><p>It looks like the adults had just as much fun with these as the children- and rightly so :) Truly there is nothing in the world quite as fun as a cardboard box.</p>
<p>Haha awesome! ;)</p>
Happy belated birthday to your little girl. Looked like it was a huge success.
<p>Too Much fun</p>
