Raisin Twist

When you need to attach a balloon to a balloon where there is no attachment point, you can create an attachment point by using the raisin twist.

Balloons needed :

On these instructions we use a 5" round.

From a peace of left over balloon create a knot. Drop it inside the 5" round.
Inflate.
Grab knot from the outside and give it a couple of twists.
Tie a peace of scrap around it. This will give you a new connection point.
