Recycling is a great way to give a new life to the things people don't want anymore. My father is good at inventing things that are practical. He made a wash stand for their garden out of 2-liter plastic soda bottles. He also made a sauna oven out of metal barrel and built a green house out of old window frames.
This year I visited my parents again (in Russia). Now, they have new "flower-beds" that my dad made out of old tires!
The tire has to be turned inside out (I do not know how he did it). The top can be cut out.
Also, this "flowerpot" can be painted. Add some soil and plant your flowers in. That's it!
But wait! You can go more "fancier"- make a swan!
I wish I had a garden here :)
