Hand sewing leather is usually done using one thread with two needles. I use waxed thread or sometimes I add bees-wax to un-waxed thread. Waxing the thread prevents it from unravelling while sewing.

Push thread through needle
To help push the thread through the needle, I cut it on an angle. The wax keeps the thread together and it makes threading the needle easier.

Pull thread through

Pierce thread
Pierce the thread. This will form a knot later and make sure that the thread stays in place.

Pull thread back

...all the way

Twist and lock into place
If you pulled it through all the way, youâll see that it formed a knot at the end of the thread (see above) and twist it to lock it in place.

Twisted thread

Done! You're ready to sew
You can use some extra bees-wax to join the thread together if it doesn’t have enough on it already. Repeat the same steps for the other end of the thread so you have 2 needles on one thread and then you’re ready for sewing!
