We may begin by cutting off the bottom portion of the Mineral water bottle using cutting blade.
Now using a sketch pen, draw a flower petal shape around the cropped portion as shown.
Now following the floral pattern cut out the flower shape using cutting knife.
Paint the floral form using golden Acrylic paint. You may paint both inside as well as outside so that the coat will turn opaque.
Using hot glue, affix a large colored stone to the center of the plastic bottle flower.
Here the Plastic flower is ready.
You may similarly make flowers using various colors to further embellish your interior space.
