Keep the loose part of the thread as far away as possible from the leather.
Does your bag or wallet show loose threads around the edges? You can remove these easily with the help of a lighter. By burning them the chances of the threads coming undone decreases, and next to that it will make your bag look better too!
Take the lighter.
Make sure its fuel is turned low so you’ll get a small flame.
Move the flame slowly towards the thread.
Burn the thread all the way down.
Lightly press the burned part with the side of the lighter.
Great job! Now the thread won’t come loose again.
