Sometimes when I?m walking the aisles of home improvement stores I get creative ideas like these basket plant stands or these table leg candlesticks. Once more it happened.
I was in the garden department and spotted some curved resin planters and thought if I put two together they?d form a nice base for an accent table. It took plastic bonder and joint compound to unite them, and here is the final result:

 
I bought all my supplies at Lowe?s including two 15? planter bases with the same circumference on top (I used these ones). In addition, here?s what you?ll need to recreate: two 24? wood circles; joint compound; 2? plastic putty knife; plastic bonder; wood glue; coarse sanding wedge; Krylon river rock spray paint.

 
To make the top, first, glue the two 24? tops with wood glue and set heavy books on top so they stay put and bond together. Allow to dry about 2 hours. Coat the wood circle sides and top with two thin layers of joint compound. It?s helpful to do this on a prop of some kind. Sand between coats and after second coat dries sand again to create a mostly smooth surface. I left mine imperfectly smooth on top because I liked the texture.

after sanding:

 
Once dry, mark the underside of the wood circles with the location of the pedestal in the center for attaching in the future.

 
To attach the planters together use a bonding glue designed for plastic (see link above). Allow to dry a few hours then use more joint compound to...
