When you open the pattern file, you may have noticed that the paper type of the surface fabric and the lining fabric of this zipper bag are different. Although they are different, the inside and outside of the bag fit perfectly. The lining of the bag is the same as the ordinary bottom corner of the zipper bag, only the surface layer to play a [transfer] game, please see the picture below left is an ordinary zipper bag, the bottom corner of the body part of the bag transferred to the bottom of the bag, it becomes the bottom corner of the zipper bag. Figure out the transfer method, I believe that your own design of the type of bag is not a problem.
