Blow up balloons to different sizes (filling balloons only halfway will help you achieve a more spherical shape) and knot each balloon. Create a drying area (Suspend a string between two chairs. Be sure to put a piece of cloth or plastic sheet under the drying area to catch any drips) Hang balloons from strings above the drying area. Apply Vaseline on the balloons (It will be easy to remove the twines later)

In a bowl, mix hot water with cornstarch, add a bottle of Fevicol MR and mix it thoroughly. Dip the twine into the glue mixture and gently squeeze out excess with your fingers.

Tie the twine at the beginning of your balloon, wrap your balloon with the wet twine. The more you wrap, the denser the ball will be. Wrap in all directions, from top to bottom and side to side When you’re satisfied with the wrapping, cut the twine.. Repeat the process with the remaining balloons Allow the balloons to dry completely. This may take about 24 hours. The twine should be stiff and dry.

Start separating the balloon from the twine and using a pin burst it. Remove the balloon form it.

String balls together using a wire and then add your lights.
