Answer 2

Bar tack is used to reinforce sing the opening and closing of pockets​.

Bar tack:

Bar tack, sometimes spelled bar-tack or bartack, is a type of stitch used in sewing to reinforce sections of a garment that are vulnerable to tension or wear.

Bar tack stitches:

• Pocket openings, buttonholes, belt loops, the bottom of fly openings, tucks, pleats, and the corner bars of the collar are all common places for tackle stitches.

• You can simply use a standard household sewing machine to secure the pocket. If you're sewing denim, you'll want to use the heaviest needle you can find or an industrial sewing machine.
