Stitch guns are used for quick sewing and tagging tasks such as hemming, repairing seams, fixing denim, altering curtains, sewing on patches, attaching garment tags and quilt labels, and general retail or craft labeling and inventory work.
Listings describe an upgraded fine needle (noted as a 5 mm fine needle) that produces very small, nearly invisible stitches suitable for hemming and discreet repairs.
Quantities vary by listing. Examples given include packs of 1,000 standard fasteners, paired packs of 1,000 black and 1,000 white fasteners, paired packs of 2,000 black and 2,000 white fasteners, and needle/pin counts listed in some kits (examples: 6 pins, 2 needles, mentions of 5 needles). Check the specific product page for exact counts.
