Flat, sew-through 2-hole buttons sized at 16 mm are a versatile choice for blouses, knitwear, children’s wear and accessories. Two holes make quick, reliable attachment while keeping a tidy look. Card includes 3 buttons. Hand-sew or use a button-sewing machine foot. On thicker fabrics, add a short thread shank under the button so the layers close easily and the garment drapes without puckering.
