I look for branches that are close to the same thickness, cut them to about 16-18 inches and first screw them together with wood screws then go over the screws with jute string. The overhead front of the trellis header has the word "welcome" that I made with sticks and short screws . The planter boxes are thick branches that I cut in half and nailed together so that the trellis will fit inside of them. I did use some 3 1/2" plastic pipes to slide the trellis into so it doesn't rot in
the dirt. We had a tornado and I got to get all the branches I wanted and the trellises sell like crazy!
