Then, I bought four 10 x 10 lego building plates.

It’s the best price I’ve seen.
Sometimes Toy’s R Us has buy one get one half off….but they are still cheaper on Amazon.
The most important step is to use legos to hold the plates together at the seams.
If you push the plates together flush, then the legos won’t work with it. They need a little tiny space. The space is super easy to get if you just use legos to hold it together while it dries and cures.
Also be sure to put heavy books or pans on the top while it dries.
