I am planning on doing this myself esp. for the my future cabbage and lettuce. I have some lettuce growing now but I am going to plant some for winter too and the cabbage so I'm going to build one to fit my garden. I have a raised garden and I just had to create one in the ground for more veggies I had ordered a month ago that just came. And I have rhubarb growing in the ground and a few veggies and herbs in pots, some outdoors and some in. So, am either going to plant them in the raised garden or in the new garden in the ground and use the frame. IF I get the chance this week, I'll try to snap a picture of it.
I see your from Michigan too. Are you Southeastern Michigan too?
