My hubby, son and I made this yesterday (saw the idea on Pinterest)! We used a piece of metal rebar as the trunk which we drilled into the large horizontal log and then drilled holes in the centre of the driftwood pieces which we then stacked. Tomorrow I'll show you it it up!
Looks wonderful.....what a fabulous idea....and, I am sorry the storm took it down, but I am sure you can put it back up again, even if the lights were damaged. The rest of it should be pretty salvageable!
