Re: Is anyone into heatstretching?
It does work but its depends on the type/make of balloons. It's also very easy to screw up! From experience you want to pre-inflate them and then lay them inside a folded foil pouch inside sn oven set to 175*c for around 5-10 minutes. These are just rough guides though, every oven is different as are balloons. It takes some experimenting to get right. I've had a 16" pastel unique reach around 30" and some 12" sempertex crystals reach aroung 18".
