You can stain or paint the boxes. I went with two different colors to go with the colors of my living room. I used spray paint for the boxes.
I stained the bottom piece even though you don't see much of it. You can spray paint it too.
Nailed the boxes to the bottom and then together. You can use a nail gun or just use small nails and hammer by hand but carefully as the wood isn't the thickest wood.
We finally had a glass top cut to size for our finishing piece. Absolutely love this table. Great decor.
