Sew the fabric together with the Singer Stitch Sew Quick to form the pocket with a 10mm margin of space from the raw cut edges of the fabric.

Leave only the pocket opening unstitched by stopping a few centimeters before it, helping to create the pocket fold.

Use the pocket that you cut out of the jacket as a reference point for what the stitching should look like.

Any standard sewing machine can be used as an alternative to the Singer Stitch Sew Quick device. Another option is hand sewing.
