I attached a photo below. Why hasn't anyone done a double stemline setup yet? You could have the bottom grid stay the same and use a tube to connect it to a second like below. You could also rotate the grid 90* to have it perpendicular to the one below it and have two tubes going up, one on each side, in possibly the shape of a heart and you could hold onto each tube like ears. I don't know just thought it was a cool "high"dea.
