Here's how it's done:
Fill fabric stiffener into a Coaster and always add about 2 - 3 m of wool to the liquid until the wool threads are completely soaked
Inflate a balloon and wrap it criss-cross with the soaked wool threads. If you work in several sections when wrapping, let the threads dry again and again before the next wrapping cycle.
Once the complete balloon is covered with a decorative grid structure and the liquid is well dried, pierce the balloon and remove the remains of the balloon with tweezers. Attach a ribbon at the top of the balloon to hang it up.
Extra tip: Hang an LED light chain in the shaped grid ball - your party light is ready.
