Just put this together today and now am trying to thaw out. It’s 51 degrees out there and lightly raining so I am all wet. I secured the sides together with an angle bracket and the door which is another pallet is secured but bungee cords. The sides hold the shovel very well. I got the idea from this cool little book called Easy Garden Projects to Make, Build, and Grow It also tells you how to make an easy aerator. It also suggests to paint it dark green to visually dissapear so once it’s stops raining that is what I am going to do.
