If you're having the wood custom cut for you at the hardware store, be sure to sand down the edges to be rounded so that anyone bumping into the table and resting their legs underneath won't get scratched.
Once the wood is prepped and ready, use a wood stain with polyurethane to stain the wood the color of your choice.
The polyurethane will help coat the wood to make it water-resistant and easier to wipe clean. Let it dry completely.
While that's drying, you can spray paint the brackets gold as well. Let those dry completely.
Going back to the wooden pieces, measure and mark from each end of the table top where you want the legs to rest underneath based on how much space is needed for your brackets.
In our case, we marked 10 inches from each end of the table to where the leg would meet the bracket, and 3 inches on either side of the leg to be centered.
Now you'll measure 3 inches in from each end of the leg closest to the outside edge on both ends. This is where the brackets will be drilled in.
Once everything is measured, you can also trace the entire leg in place because you're going to be removing it to apply the Liquid Nails and then putting it back in place.
Squeeze a generous amount of liquid nails onto one edge of the legs, making sure that it's not so much that it will overflow on either edge once it's pressed down onto the table.
Let it set completely before installing the brackets on either edge.
While you're waiting, you can apply felt pads to the bottom of the table legs for easy maneuvering when it's complete.
Once set, place the brackets on your measurement marks, and screw to the tabletop first. This will make drilling into the legs easier after that.
When all the brackets are screwed in place, place the four 90 degree angle brackets on the opposite side of the legs lining up with each curved bracket, and screw those in place.
