Drawing of design

My final design is probably going to be the bottle cap one because plastic has a bigger impact on our earth and plastic links well to the tree as well because plastic pollutes soil and that could impact the way trees grow and also because I already had a lot of plastic bottles lying around so the materials were easier to collect . I intend to use the colours blue and maybe green becuase that's the colour of most of my bottle caps. I will collect my materials by collecting the caps of the plastic bottles I use.
