From one side, gently slide the stick over the sides and under the nose piece of your topper as shown.

Allow them to sit awhile and gently get accustomed to that slight curve.

1. Use a heating pad on low to medium heat, a Ziplock bag of hot tap water, a blow-dryer, or even the sunlight to gently heat your toppers.

2. When warmed, place them onto your frames and gently press topper and frame into a cool pillow.

3. Hold for a few minutes and check to see if they have formed to your frame.

4. Repeat if necessary.
