These are great. It took me longer than expected to put it together, but only because I’m not used to doing such things. I bought a second set to add to the top to make it feel more sturdy, and I’m very happy with it. I put the solid side on the outside and it works just as well. I did 12 feet for the length and 2 feet for the width. If I were to make another one I would shorten the width to 1 1/2 feet or shorter.
