You can generally make this into whatever shape you want, just make sure it isn't vertical and the jump isn't too sharp. You want a slightly curved drop and a curved part at the bottom to a jump! the ramp will need to be supported by the pieces you cut off earlier. Take one of them and tape it under the jump part at whatever angle you want it to be. If your parents allow it you can tape it straight to the ground with the duct tape, this will work better but IT WILL LEAVE THE GROUND STICKY. Otherwise you can take the paper you have and tape it to the ground with scotch tape and tape the ramp support to that. The picture for this step has the perfect shape so look at that for help.
