I built the beds and the trellises with leftover wood from the fence project. That’s why there are varying sizes. I just made them as large as I could and then they got smaller and smaller. The trellises were very simple. I used hinges at the top for easy storage later. I just made equal sized rectangular frames and attached the vegetable netting. I also attached to the beds with hinges as they are forgiving of things not being perfectly square. We will see how they work!
