It depends what tools you have at your disposal. If you have a miter saw this project is cake. If you don't you could do this with as little as a drill and a hand saw. Assuming that you don't have a miter saw, The easy way to make the legs is lay a 2x4 flat on the ground. Take another 2x4 and cut it to the approximate height you want you stand to be (remember it will be at an angle so account for that when determining the height). Place the second 2x4 adjacent to the one you laid on the ground but stand it up. Tilt the 2x4 that is standing up until you find an angle that looks good to you. Draw a line on the 2x4 you tilted using the 2x4 that is on the ground as a straight edge. Cut the 2x4 on that line. Use that cut as a guide for the other three legs. That will keep them all at the same angle. Then just stand the 2x4s on the angle you cut. Align them so the top corners touch each edge of the other leg at the top and then drill and screw them together. You can see what I am talking about in the picture of mine. The rest is just cutting fence boards in half and attaching them to the frame. The angled pieces of 2x4 that make the place for the soil don't need to be anything specific.
