Use the tape measure and find the center of the 12in wooden round. Using a drill bit slightly smaller than than the screw on the furniutre leg, drill halfway through the 12in round.
Add some wood glue around the screw on the furniture leg and screw the furniture leg into the 12in round until it fits tight.
Using the tape measure mark the center on the 4in and 5in round plaques.
Drill a hole all the way through both of the plaques and partially into the bottom of the furniture leg.
Add some wood glue to both of the plaques around the holes and to the bottom of the leg.
Take your 2.5in screw and screw the 5in into the 4in up into the leg until it is tight.
Using your paintbrush, apply the stain to the whole cake stand. Let the stain soak in and then wipe back any remaining stain with a clean rag.
Once the stain has dried apply the Annie Sloan White Wax to the leg and plaques with a brush. Let sit for a few minutes then take a clean rag and wipe off the excess.
I then applied a buther block sealer to the top of the cake stand to protect it.
Notes
I still always cut a round piece of parchment to lay down before I put my food on it.
