We're actually done but I stuck my other camera on its dock to charge and I can't get at the last pics. So now you have to wait until tomorrow to see the finished greenhouse. We used wood strips to fold the plastic under and to secure to the frame. This was a great idea from my dad.
Here the guys are figuring out how to secure the plastic around the door.
We used 6mm clear plastic from the hardware store. This is thick plastic but you still need to take care that it doesn't rip! We were able to use one piece for our project.
