STEP 1: Place pine round
First, I placed my pine round in my whiskey barrel planter. You can use anything round to replace the pine round such as a pizza pan. Depending on what you’re going to fill the top of your planter with, you’ll want to have space between the pine round (or pizza pan) and the top edge of your planter. I needed quite a bit of space because of how bulky my wine corks were so the 17-3/4″ pine round gave the perfect amount of space from the top edge of the planter.
