Here’s where the magic happens! Grab your hairdryer (high heat) or heat gun (medium heat) and start applying heat to the bottom of the bottle. Rotate the bottle slowly in a spiral motion, working your way up to the top. The slower you go, the better the results will be. If you don't start from the bottom or go slow, your results will suffer. Also, when you start shrinking the upper portion, be sure to hold the wrap at the top with your other hand to avoid any unwanted wrinkles! Pro Tip: If you want a super smooth finish after you are done with your heat gun, boil water in a tea pot and pour it over the bottle wrap in your sink. This will shrink the wrap perfectly! This is also a great way to remove any wrinkles from the wrap.
