For our stand, we wanted to create a tree look with three staggered dowel lengths on each face. From the top of each face, we marked at;
Face 1: 50mm, 250mm, 450mm
Face 2: 100mm, 200mm, 300mm
Face 3: 150mm, 350mm, 550mm
Face 4: 200mm, 400mm, 600mm
Square off a line at each mark across the timber and then mark a 45-degree angle on the side.
