Moccasins, sew the top

After we have prepared all the parts of the moccasins and tried the holes, we start assembling the shoes. First of all we sew the top to the bottom. If you have not guessed with the size, sewing a heel can be adjusted on a leg.
I use the counter seam. Need two needles and a shoe thread. There is a special thread, it is flat, but if it is not available, you can also use a conventional round one. The shape of the thread on the quality does not affect, only the appearance.

The thread should be tightened well, but not overtightened so that the top does not wrinkle.
