When a piece already has feet or legs, there isn't a ton you can do beside maybe add a 'skirt' to the base and then reattach the feet like we did on this dresser, or add casters.
We did that a few weeks back to add height to this buffet that was being used as an island and I thought it would be a good option for this coffee table.
Feet before drilling for casters.
I measured how long the casters were, put a piece of tape around the drill bit so I could drill down and stop at the correct depth.
I did start with a smaller bit and worked my way up to a larger bit to make things easier.
Holes all done!
I ordered a nice piece of glass to fit on top of the table to help protect the glazed finish because this table will have a lot of feet resting on it and drinks.
