We bought two corbels at Home Depot like this.
We added trim, like the kind we used on our built in bathroom shelving, to the edges of the floating shelf and attached the corbels to the bottom. I spray painted the whole thing with basic white spray paint. I WAS NOT going to try and coat every nook and cranny of those corbels with a paint brush. Here’s a closeup of the underside of the shelf so you can see how it all went together.
Please accept my apologies for no pictures of us actually making this thing. There was a baby to contend with and we just wanted to get it done. But, this is so simple y’all, you really don’t need step by step photos.
Grunt Labor finally hung it on the wall:
Whadda ya think? By the way, that julep cup and lamp are both Goodwill finds! Score!
