Place a drop of the same glue over each place that was glued back, and put one of the blister pieces we cut. If you used the aluminum coated part of the blister, make sure the aluminum is on the outside, not facing the glue.

You may need to also do this on the other end of the stems for some buttons if you notice they show sign of wear.

Repeat for each button cap.

Let it dry (up to 24 hours).

Put it all back in reverse order.

Remove the cardboard pieces holding the button caps.
