Processing of a welt pocket with a leaflet.
The meaning of this treatment is that there are no visible cut allowances of the pocket frame, they are all closed inside the pocket, which creates a beautiful and clean treatment.
You can not glue the reinforcement strip from the doubler to the second burlap, it will look more aesthetically pleasing, but I am for a strong, high-quality process during wear and therefore glued it.
Instead of a doublerine dolevik, you can use a lining fabric, polyester, and then the burlap is already covered with it.
There are many different ways of processing a pocket and one method, my favorite, I showed you.
