STEP 1
Keep the loose part of the thread as far away as possible from the leather.

STEP 2
Take the lighter.
Make sure its fuel is turned low so you’ll get a small flame.

STEP 3
Move the flame slowly towards the thread.
Burn the thread all the way down.

STEP 4
Lightly press the burned part with the side of the lighter.
Great job! Now the thread won’t come loose again.
