THINGS YOU REQUIRE:
Glass bottle, paper threads (any colour of your choice), and an adhesive.
Take a glass bottle and clean it well.
Get paper threads as shown in the picture (you may get it at any stationary shop), and choose a suitable colour combination.
Apply adhesive (bit by bit) to the entire bottle in a circular fashion and simultaneously keep sticking the thread.
Neatly stick the thread, making sure that no gaps are left.
Reach to the top of the bottle and stick the thread at the end by applying some extra glue. Make sure that the end is not visible.
You can combine and form various colour patterns like this.
TIP: The paper threads give a raw look to the bottle. If you are looking for something elegant, you may try out laces as shown in the picture.
