Preheat your oven to 300 degrees F (150 degrees C).
Grab ahold of one wrapper securely in a pair of tongs.
Open the oven door, and extend the confectionery wrapper into the oven with the tongs.
Keep a watchful eye, as the wrappers shrink rapidly.
Remove the tongs and wrapper from the oven a split second before they achieve your desired size. Even outside the oven, the wrapper will continue to shrink for a moment.
- This procedure might be more easily and safely performed with a microwave.
