An Italian factory uses a specialized machine to stitch 3D welt pockets onto garments. The machine layers base fabric with silk or polyester lining and stitches them together automatically. Pocket placement must be exact or the whole garment fails.
What he's doing right now is he's following the pattern to denote where all the pocketing is gonna go. This is a very, very important step because they need to place the pockets just right, but also because these pockets are 3D-like pockets that are sewn in a very specific way. It needs to be extremely precise or it's gonna be a complete mess. So this machine over here is rigged up to automatically make the pockets. In this case, it's going to be a different fabric for the pocket. The base fabric goes down, the actual silk for the pocket goes in. Or in this case it's a polyester, and it's all automatically programmed to create that welt pocket. And just like that, she's created a welt pocket seamlessly.
