So, you've got a big wooden planter and don't want to put actual plants on it. What to do, what to do?
First take some river rocks and throw them in there. Then, pour some clear acrylic over them:
Lots and lots of acrylic...
Then, stick some huge vases in and add some more acrylic... And throw some dead/dried flowers in there. It'll be lovely!
