That works in the same way (almost) as a sewing machine.
Load the bobbin with thread and thread it through the needle. On the first hole of the stitch, insert the needle into the hole and exit the other side. Pull the lose end of the thread all the way to the other side. Pull the needle out of the hole. Now you have automatic awl on one side and the end of the thread on the other. Pull the thread to suit the length of the stitch.
Now on the second and subsequent stitch hole, you push the awl into the hole almost to the end, and pull back until you get a loop in the thread. Then you thread the lose end of the thread into this loop. pull the awl out and tighten the stitch.
hope that is clear. Never try it myself thought
