Bunny Barn roof upgrade

Today I'm upgrading the roof of my temporary "Bunny Barn" from a heavy duty tarp, to a pond liner. the tarp has broken down over time to the point where it's allowing rain to seep through it. I purchased a pond liner to cover most of the bunny barn it's a grommet kit to install grommets so that I could wire tie the pond liner in place. hopefully this will get me many years of waterproofing underneath.
